Build crt*vr.S with AltiVec enabled

These files won't build on targets that do not have AltiVec enabled,
breaking the build, unless we tell GAS that Altivec insns are fine.
The alternative is to not build these files in that case, which is much
more complicated.

libgcc/
	* config/rs6000/crtrestvr.s: Use .machine altivec.
	* config/rs6000/crtsavevr.s: Ditto.
