PPC: Ignore spill/restore requests for VRSAVE (except on Darwin)
This fixes PR16418, which reports that a function calling
__builtin_unwind_init() asserts. The cause is that this generates a
spill/restore for VRSAVE, and we support that only on Darwin (because VRSAVE is
only really used on Darwin).
The test case checks only that we don't crash. We can add correctness checks
once someone verifies what behavior the function is supposed to have.
