Use entrypoint switching to reduce code size of GcRoot read barrier
Set the read barrier mark register entrypoints to null when the GC
is not marking. The compiler uses this to avoid needing to load the
is_gc_marking boolean.
Code size results on ritzperf CC:
arm32: 13439400 -> 13242792 (-1.5%)
arm64: 16380544 -> 16208512 (-1.05%)
Implemented for arm32 and arm64. TODO: Consider implementing on x86.
