Fixed.

We already have such tests. See e. g. on lines 6883-6890 in
gas/testsuite/gas/i386/avx512f.s we have:

	vcvtps2ph	$0xab, %zmm6, (%ecx)	 # AVX512F
	vcvtps2ph	$0xab, %zmm6, (%ecx){%k7}	 # AVX512F
	vcvtps2ph	$123, %zmm6, (%ecx)	 # AVX512F
	vcvtps2ph	$123, %zmm6, -123456(%esp,%esi,8)	 # AVX512F
	vcvtps2ph	$123, %zmm6, 4064(%edx)	 # AVX512F Disp8
	vcvtps2ph	$123, %zmm6, 4096(%edx)	 # AVX512F
	vcvtps2ph	$123, %zmm6, -4096(%edx)	 # AVX512F Disp8

Do we need additional tests?

Subject: [PATCH] Remove bogus vcvtps2ph variant.

We currently support version of vcvtps2ph with sae and only 1 register operand.
This version is encoded as if missing operand was equal to ymm0.
I didn't found any references to this variant in
http://download-software.intel.com/sites/default/files/managed/50/1a/319433-018.pdf
This patch removes it.
