As described in the PR, cc1 SEGVs compiling gcc.dg/rtl/x86_64/final.c on
targets that default to -fno-dwarf2-cfi-asm. However, the test is
compile-only, so doesn't depend on the toolchain's support for cfi
directives. Besides, it scans the output for those, so depends on
-fdwarf2-cfi-asm anyway, so I'm adding it explicitly.
Tested with the appropriate runtest invocation on i386-pc-solaris2.11
with as (-fno-dwarf2-cfi-asm default), gas (-fdwarf2-cfi-asm default),
and x86_64-pc-linux-gnu.
Ok for mainline and gcc-7 branch?
