X86_64: Add allocation entrypoint switching for CC is_marking

Only X86_64 done so far. Use normal TLAB allocators if GC is not
marking.

Allocation speed goes up by ~8% based on perf sampling.

Without change:
1.19%: art_quick_alloc_object_region_tlab

With change:
0.63%: art_quick_alloc_object_tlab
0.47%: art_quick_alloc_object_region_tlab
