Darwin, X86: Adjust call clobbers to allow for lazy-binding [PR 100152].
We allow public functions defined in a TU to bind locally for PIC
code (the default) on 64bit Mach-O.
If such functions are not inlined, we cannot tell at compile-time if
they might be called via the lazy symbol resolver (this can depend on
options given at link-time). Therefore, we must assume that the lazy
resolver could be used which clobbers R11 and R10.

gcc/ChangeLog:
PR target/100152
* config/i386/i386-expand.c (ix86_expand_call): If a call is
to a non-local-binding, or local but to a public symbol, then
assume that it might be indirected via the lazy symbol binder.
Mark R10 and R10 as clobbered in that case.
