Disable the "call to immediate" optimization on x86-64. It is
not safe in general because the immediate could be an arbitrary
value that does not fit in a 32-bit pcrel displacement.
Conservatively fall back to loading the value into a register
and calling through it.
We still do the optzn on X86-32.
