Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, DW_AT_APPLE_flags.
DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way. DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by a project, irrespective of whether the project used makefile, Xcode or something else. llvm-gcc patch is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62888 91177308-0d34-0410-b5e6-96231b3b80d8
