Adrian Prantl d50d56c774 Driver/Darwin: Set the DWARF version based on the deployment target. 
System utilities such as atos only support DWARF 4 on OS X 10.11+ and
iOS 9+. We thus want to enable DWARF 4 only if the deployment target
has a recent enough operating system version and use DWARF 2 for older
systems.

Adrian Prantl 432d3d2619 Debug info: Bump the default DWARF version on Darwin to 4. 
This is a spiritual re-commit of r201375 with only a brief delay
for upgrading the green dragon builders.

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.

Brad Smith 378e7f9b78 Use dwarf-2 by default on OpenBSD and FreeBSD. 
The Tools.cpp part of the patch partially based on a patch from
FreeBSD's LLVM tree.

Adrian Prantl 549c514799 Revert "Debug info: Make DWARF4 the default for Darwin, too." 
I'm holding this change to give maintainers of Darwin buildbots more time
to update their toolchains.

This reverts commit r201375.

Manman Ren 38db092083 Debug Info: set default to gdwarf-2 for Darwin. 
Darwin systems currently do not support dwarf version 3 or above. When we are
ready, we can bump the default to gdwarf-4 for Darwin.

For other systems, the default is dwarf version 3, if everything goes smoothly,
we can bump the version to 4.
