[Driver] Default Generic_GCC ppc/ppc64/ppc64le to -fasynchronous-unwind-tables

Authored by MaskRay on Nov 24 2020, 12:03 PM.



GCC made the switch on 2018-04-10 ("rs6000: Enable -fasynchronous-unwind-tables by default").
In Clang, FreeBSD/NetBSD powerpc have already defaulted to -fasynchronous-unwind-tables.

This patch defaults Generic_GCC powerpc (which affects Linux) to use -fasynchronous-unwind-tables.
