expand: Small speed up expansion of __builtin_prefetch
This is a small speed up of the expansion of __builtin_prefetch.
Basically for the optional arguments, no reason to call expand_normal
on a constant integer that we know the value, just replace it with
GEN_INT/const0_rtx instead.
Bootstrapped and tested on x86_64-linux.
gcc/ChangeLog:
* builtins.cc (expand_builtin_prefetch): Rewrite expansion of the optional
arguments to not expand known constants.
