New Revision: 63221

URL: http://llvm.org/viewvc/llvm-project?rev=63221&view=rev
Log:

Undo following patch for now.

----
Set DW_AT_APPLE_optimized and DW_AT_APPLE_flags attribute while building
DICompileUnit.

Right now, llvm-gcc does not emit debug info when optimization is ON. However,
emit llvm.dbg.compile_unit and preserve it even when optimization is ON. This
allows DW_AT_APPLE_flags to find its way in final binary.
