Jim Ingham 5e09c8c32c Add the ability to tag one or more breakpoints with a name. These
names can then be used in place of breakpoint id's or breakpoint id 
ranges in all the commands that operate on breakpoints.

Enrico Granata a6a1d5a623 Provide a SBFrame.register/.reg helper on the Python side of SBFrame to vend a flattened view of registers
Our actual view of registers is a set of register sets, each one of which contains a subset of the actual registers
This makes trivial scripting operations tedious ("I just want to read r7!")

This helper allows things like: print lldb.frame.reg["r7"]

Fixes rdar://19185662

Enrico Granata 0c10a85000 Add the ability for an SBValue to create a persisted version of itself.
Such a persisted version is equivalent to evaluating the value via the expression evaluator, and holding on to the $n result of the expression, except this API can be used on SBValues that do not obviously come from an expression (e.g. are the result of a memory lookup)

Expose this via SBValue::Persist() in our public API layer, and ValueObject::Persist() in the lldb_private layer

Includes testcase

Enrico Granata 49bfafb510 Shuffle APIs around a little bit, so that if you pass custom summary options, we don't end up caching the summary hence obtained. You may want to obtain an uncapped summary, but this should not be reflected in the summary we cache. The drawback is that we don't cache as aggressively as we could, but at least you get to have different summaries with different options without having to reset formatters or the SBValue at each step

Greg Clayton 8012cadbf3 Fixed more fallout from running the test suite remotely on iOS devices.
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener. 
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:

    size_t
    Target::UnloadModuleSections (const ModuleList &module_list);

    size_t
    Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

Enrico Granata c1247f5596 Introduce the notion of "type summary options" as flags that can be passed down to individual summary formatters to alter their behavior in a formatter-dependent way
Two flags are introduced:
- preferred display language (as in, ObjC vs. C++)
- summary capping (as in, should a limit be put to the amount of data retrieved)

The meaning - if any - of these options is for individual formatters to establish
The topic of a subsequent commit will be to actually wire these through to individual data formatters

Matthew Gardiner c928de3e8e Added functions to the C++ API, for the benefit of non-8-bit byte architectures.
New functions to give client applications to tools to discover target byte sizes
for addresses prior to ReadMemory. Also added GetPlatform and ReadMemory to the
SBTarget class, since they seemed to be useful utilities to have.

Each new API has had a test case added.

Jim Ingham ffc9f1de34 This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger
after all the commands have been executed except if one of the commands was an execution control
command that stopped because of a signal or exception.

Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext.  That
way you can run an lldb command targeted at a particular target, thread or process w/o having to 
select same before running the command.

Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that
seemed generally useful.

Kuba Brecka 6392754839 Add a IsInstrumentationRuntimePresent SB API
Reviewed at http://reviews.llvm.org/D5738

This adds an SB API into SBProcess:
  bool SBProcess::IsInstrumentationRuntimePresent(InstrumentationRuntimeType type);
which simply tells whether a particular InstrumentationRuntime (read "ASan") plugin is present and active.

Jim Ingham 26c7bf9312 Rework the way we pass "run multiple command" options to the various API's that
do that (RunCommandInterpreter, HandleCommands, HandleCommandsFromFile) to gather
the options into an options class.  Also expose that to the SB API's.

Change the way the "-o" options to the lldb driver are processed so:
1) They are run synchronously - didn't really make any sense to run the asynchronously.
2) The stop on error
3) "quit" in one of the -o commands will not quit lldb - not the command interpreter
that was running the -o commands.

I added an entry to the run options to stop-on-crash, but I haven't implemented that yet.

Kuba Brecka afdf842b3f LLDB AddressSanitizer instrumentation runtime plugin, breakpint on error and report data extraction
Reviewed at http://reviews.llvm.org/D5592

This patch gives LLDB some ability to interact with AddressSanitizer runtime library, on top of what we already have (historical memory stack traces provided by ASan). Namely, that's the ability to stop on an error caught by ASan, and access the report information that are associated with it. The report information is also exposed into SB API.

More precisely this patch...

adds a new plugin type, InstrumentationRuntime, which should serve as a generic superclass for other instrumentation runtime libraries, these plugins get notified when modules are loaded, so they get a chance to "activate" when a specific dynamic library is loaded
an instance of this plugin type, AddressSanitizerRuntime, which activates itself when it sees the ASan dynamic library or founds ASan statically linked in the executable
adds a collection of these plugins into the Process class
AddressSanitizerRuntime sets an internal breakpoint on __asan::AsanDie(), and when this breakpoint gets hit, it retrieves the report information from ASan
this breakpoint is then exposed as a new StopReason, eStopReasonInstrumentation, with a new StopInfo subclass, InstrumentationRuntimeStopInfo
the StopInfo superclass is extended with a m_extended_info field (it's a StructuredData::ObjectSP), that can hold arbitrary JSON-like data, which is the way the new plugin provides the report data
the "thread info" command now accepts a "-s" flag that prints out the JSON data of a stop reason (same way the "-j" flag works now)
SBThread has a new API, GetStopReasonExtendedInfoAsJSON, which dumps the JSON string into a SBStream
adds a test case for all of this
I plan to also get rid of the original ASan plugin (memory history stack traces) and use an instance of AddressSanitizerRuntime for that purpose.

Jim Ingham 2bdbfd50d2 This checkin is the first step in making the lldb thread stepping mechanism more accessible from
the user level.  It adds the ability to invent new stepping modes implemented by python classes,
and to view the current thread plan stack and to some extent alter it.

I haven't gotten to documentation or tests yet.  But this should not cause any behavior changes
if you don't use it, so its safe to check it in now and work on it incrementally.
