i386: i386-expand formatting fixes

While working on the PR105214 patch, I've noticed incorrect formatting
for a bunch of functions where the function names aren't at the start of
lines.

The following patch fixes it, though of course it isn't a regression.

2022-04-12  Jakub Jelinek  <jakub@redhat.com>

	* config/i386/i386-expand.cc (ix86_emit_i387_sinh, ix86_emit_i387_cosh,
	ix86_emit_i387_tanh, ix86_emit_i387_asinh, ix86_emit_i387_acosh,
	ix86_emit_i387_atanh, ix86_emit_i387_log1p, ix86_emit_i387_round,
	ix86_emit_swdivsf, ix86_emit_swsqrtsf,
	ix86_expand_atomic_fetch_op_loop, ix86_expand_cmpxchg_loop):
	Formatting fix.
	* config/i386/i386.cc (warn_once_call_ms2sysv_xlogues): Likewise.
