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

// RUN: %clang_cc1 -emit-llvm -debug-info-kind=limited %s -o - | FileCheck %s
Debug info: (Bugfix) Make sure artificial functions like _GLOBAL__I_a are not associated with any source lines. Previously, if the Location of a Decl was empty, EmitFunctionStart would just keep using CurLoc, which would sometimes be correct (e.g., thunks) but in other cases would just point to a hilariously random location. This patch fixes this by completely eliminating all uses of CurLoc from EmitFunctionStart and rather have clients explicitly pass in a SourceLocation for the function header and the function body. rdar://problem/14985269 llvm-svn: 205999

Follow-up to r205999: Emit an artificial location (valid scope, line 0) for CXXGlobalInit/Dtor helper functions. This makes _GLOBAL__I_a regain its DW_AT_high/low_pc in the debug info. Thanks to echristo for catching this! llvm-svn: 206088

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. This commit was generated using the rename-md-di-nodes.sh upgrade script attached to PR23080, followed by running clang-format-diff.py on the `lib/` portion of the patch. llvm-svn: 236121
