Douglas Katzman 3459ce2e5e 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.

Nick Lewycky ba743b75cb Take DW_AT_comp_dir from $PWD when it's present and starts with a '/'. This is 
closer to what GCC does, except that GCC also checks that the inodes for $PWD
and '.' match.
