i386: Fix up vpternlogq last operand of *andnot<mode>3 for -masm=intel [PR124367]

Browse Source 
The immediate operand 0x44 in this insn was incorrectly emitted as
$0x44 even in -masm=intel syntax.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
approved by Uros in the PR, committed to trunk.

2026-03-05  Jakub Jelinek  <jakub@redhat.com>

	PR target/124367
	* config/i386/sse.md (*andnot<mode>3): Use 0x44 rather than $0x44
	for -masm=intel.

	* gcc.target/i386/avx512vl-pr124367.c: New test.
