testsuite: i386: Adjust gcc.target/i386/cmov12.c for Sun as syntax

The new gcc.target/i386/cmov12.c test FAILs on Solaris/x86 with the
native as:

FAIL: gcc.target/i386/cmov12.c scan-assembler-times cmovg 3

This happens because as uses a different syntax for cmov:

+++ cmov12.s.bu24390	2025-01-21 16:55:44.565051230 +0100

The problem is even more prominent with the upcoming gas 2.44 which
added support for the Sun as syntax on Solaris, which gcc/configure
picks up.

This patch allows for both forms.

Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.

	* gcc.target/i386/cmov12.c (scan-assembler-times): Allow for
	cmovl.g etc.
