[dev.typeparams] all: always enable regabig on AMD64
Always enable regabig on AMD64, which enables the G register and
the X15 zero register. Remove the fallback path.
Also remove the regabig GOEXPERIMENT. On AMD64 it is always
enabled (this CL). Other architectures already have a G register,
except for 386, where there are too few registers and it is
unlikely that we will reserve one. (If we really do, we can just
add a new experiment).
