[Driver] Add -gno-split-dwarf which can disable debug fission

Authored by MaskRay on Dec 7 2020, 7:25 PM.



Currently when -gsplit-dwarf is specified (could be buried in a build system),
there is no convenient way to cancel debug fission without affecting the debug
information amount (all of -g0, -g1 -fsplit-dwarf-inlining, and -gline-directives-only
can, but they affect the debug information amount).
