Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

DebugInfo: Metadata constructs now start with DI* LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week.

DebugInfo: Adapt to loss of DITypeRef in LLVM r267296 LLVM stopped using MDString-based type references, and DIBuilder no longer fills 'retainedTypes:' with every DICompositeType that has an 'identifier:' field. There are just minor changes to keep the same behaviour in CFE. Leaving 'retainedTypes:' unfilled has a dramatic impact on the output order of the IR though. There are a huge number of testcase changes, which were unfortunately not really scriptable. llvm-svn: 267297

DI: Update testcases for LLVM assembly change Update testcases after LLVM change r243774. Most of these had no need to check `tag:` field, but did so as a way of getting to the `name:` field. In a few cases I've converted the `tag:` checks to `arg:` or `CHECK-NOT: arg:`. llvm-svn: 243775
