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

Debug info: pass in the correct size for a pointer to a member function. This corrects a bug I introduced in r224781. llvm-svn: 225359

[MS ABI, DebugInfo] Omit the size for model-less pointers-to-members The representation of a pointer-to-member in the MS ABI is governed by the layout of the relevant class or if a model has been explicitly specified. If no model is specified, then an appropriate "worst-case-scenario" model is implicitly chosen if, and only, if the pointer-to-member type's representation was needed. Debug info cannot force a pointer-to-member type to have a representation so do not try to query the size of such a type unless we know it is safe to do so. llvm-svn: 238259
