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

// Verify that the global init helper function does not get associated
// with any source location.

Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971

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
