rtl: builtins: Fix builtins feclearexcept and feraiseexcept operand check [PR94193]
Commit 4343f5e25679 ("rtl: builtins: (not just) rs6000: Add builtins
for fegetround, feclearexcept and feraiseexcept [PR94193]") broke gcc
bootstra when building with --enable-checking=rtl[1].
The function expand_builtin_feclear_feraise_except was failing to
proper validate op0 predicate before emit_insn leading to the mismatch
type failure.
