The following change lets you provide a spec in xm-foo.h analogous to
the CC1_SPEC, but specific to invocation of cc1plus.  For example,

#define CC1PLUS_SPEC "-fdefault-inline -felide-constructors -fmemoize-lookups -fsave-memoized"

I left CC1_SPEC in, since in terms of arguments accepted cc1plus seems
to be a superset of cc1, and most of the arguments to cc1 would make
sense to cc1plus also.  (Those that might not, like `-pedantic', are
still accepted anyways.)  If for some reason an option in CC1_SPEC is
not wanted for cc1plus, CC1PLUS_SPEC can override it (in most cases)
with a `no-' option.

The original source file is the gcc.c distributed with g++ 10/17.
