"Allow LanguageRuntimes to return an error if they fail in the course of dynamic type discovery
This is not meant to report that a value doesn't have a dynamic type - it is only meant as a mechanism to propagate actual type discovery issues (e.g. malformed type metadata for languages that have such a notion)
This information is used by ValueObjectDynamic to set its own m_error, which is a fairly sharp and heavyweight tool to begin with
For the time being, this is an architectural improvement but a practical no-op as no existing runtimes are actually setting errors"
I need to think about what I want to do in this space more carefully - this attempt might be too heavy of a hammer for the nail I am trying to fix, and I don't want to leave it in while I ponder

Currently it is not specified, and since allocations are usually
requested once we hit a renderscript breakpoint, the language will be
inferred being as renderscript by the ExpressionParser.
Actually allocations attempt to invoke functions part of the RS runtime,
written in C/C++, so evaluating the calls in RenderScript could be
misleading.
In particular, in MIPS, the ABI between C/C++ (mips o32) and
renderscript (arm) might introduce subtle bugs when evaluating such
expressions.
This change explicitly sets the language used to evaluate the allocations
as C++.

Mips64 tests were failing on windows because the sscanf implementation differs between clang/gcc/msvc such that on windows %lx specifies a 32bits parameter and %llx is for 64bits. For us this meant that 64bit pointers were being truncated to 32bits on their way into a JIT'd expression.

This patch reworks the function argument reading code, allowing us to annotate arguments with their types. The type/size information is needed to correctly parse arguments passed on the stack.

Obviously, if the original Debugger goes away, those commands are holding on to now stale memory, which has the potential to cause crashes
Fixes rdar://24460882

Patch replaces the --refresh flag removed in r258800 with it's own command, 'language renderscript allocation refresh'.
Since there is no reason this functionality should be tied to another command as an option.
The command itself simply re-JITs all our cached information about allocations.

Patch deletes the 'language renderscript module probe' command.
This command was present in the initial commit to help debug the plugin.
However we haven't used it recently and it's functionality is unclear, so can be removed entirely.
Also add back 'kernel coordinate' command, removed by accident in clang format patch r259056.
llvm-svn: 259181
Patch replaces the 'renderscript allocation list' command flag --refresh, with a new option --id <ID>.
This new option only prints the details of a single allocation with a given id, rather than printing all the allocations.
Functionality from the removed '--refresh' flag will be moved into its own command in a subsequent commit.

std::array should have "the same semantics as a struct holding a C-style array T[N] as its only
non-static data member", so the initialization should have one more level of braces. Hopefully,
no compiler will object to that.
llvm-svn: 258306
Patch adds command 'language renderscript kernel coordinate' for printing the kernel index in (x,y,z) format.
This is done by walking the call stack and looking for a function with suffix '.expand', as well as the frame variables containing the coordinate data.

Reverts earlier commit r254910, which used function pointers for jitted expressions
to avoid a Mips64 compiler bug. Bug has since been fixed, and compiler longer issues the problem instruction.

Updates the file format for storing RS allocations to a file, so that the format now supports struct element types.
The file header will now contain a subheader for every RS element and it's descendants.
Where an element subheader contains element type details and offsets to the subheaders of that elements fields.
Patch also improves robustness when loading incorrect files.
