Pavel Labath 145d95c964 Move Args.cpp from Interpreter to Utility
Summary:
The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.

This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

Davide Italiano 24fff2429c [Command] Implement statistics command.
This allows us to collect useful metrics about lldb debugging sessions.

I thought that an example would be better than a thousand words:

  Process 19705 stopped
  * thread #1, queue = 'com.apple.main-thread', stop reason = step in
      frame #0: 0x0000000100000fb4 blah`main at blah.c:3
     1    int main(void) {
     2      int a = 6;
  -> 3      return 0;
     4    }
  (lldb) statistics enable
  (lldb) frame var a
  (int) a = 6
  (lldb) expr a
  (int) $1 = 6
  (lldb) statistics disable
  (lldb) statistics dump
  Number of expr evaluation successes : 1
  Number of expr evaluation failures : 0
  Number of frame var successes : 1
  Number of frame var failures : 0

Future improvements might include:

1. Passing a file, or implementing categories. The way this patch has
been implemented is generic enough to allow this to be extended
easily without breaking the grammar.
2. Adding an SBAPI and Python API for use in scripts.

Thanks to Jim Ingham for discussing the design with me.

Pavel Labath 38d0632e6a Move Timer and TraceOptions from Core to Utility
Summary:
The classes have no dependencies, and they are used both by lldb and
lldb-server, so it makes sense for them to live in the lowest layers.

Zachary Turner 97206d5727 Rename Error -> Status.
This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too
serious.

r285226 dropped the code that did these checks.  I am pretty
sure that was inadvertent, so I added that back in and added
a test for it.

Zachary Turner bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

Zachary Turner 1c55c9b5bf Add the new Args / entry-access API.
The long-term goal here is to get rid of the functions
GetArgumentAtIndex() and GetQuoteCharAtIndex(), instead
replacing them with operator based access and range-based for
enumeration.  There are a lot of callsites, though, so the
changes will be done incrementally, starting with this one.

It doesn't like the implicit conversion from T[] to ArrayRef<T>

Zachary Turner 1f0f5b5b9e Convert option tables to ArrayRefs.
This change is very mechanical.  All it does is change the
signature of `Options::GetDefinitions()` and `OptionGroup::
GetDefinitions()` to return an `ArrayRef<OptionDefinition>`
instead of a `const OptionDefinition *`.  In the case of the
former, it deletes the sentinel entry from every table, and
in the case of the latter, it removes the `GetNumDefinitions()`
method from the interface.  These are no longer necessary as
`ArrayRef` carries its own length.

In the former case, iteration was done by using a sentinel
entry, so there was no knowledge of length.  Because of this
the individual option tables were allowed to be defined below
the corresponding class (after all, only a pointer was needed).
Now, however, the length must be known at compile time to
construct the `ArrayRef`, and as a result it is necessary to
move every option table before its corresponding class.  This
results in this CL looking very big, but in terms of substance
there is not much here.

This updates getters and setters to use StringRef instead of
const char *.  I tested the build on Linux, Windows, and OSX
and saw no build or test failures.  I cannot test any BSD
or Android variants, however I expect the required changes
to be minimal or non-existant.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.
