x86: Properly set YMM/ZMM features

Browse Source 
Since VEX/EVEX vector instructions will always update the full YMM/ZMM
registers, set YMM/ZMM features for VEX/EVEX vector instructions.

	* config/tc-i386.c (output_insn): Set YMM/ZMM features for
	VEX/EVEX vector instructions.
	* testsuite/gas/i386/property-4.d: New file.
	* testsuite/gas/i386/property-4.s: Likewise.
	* testsuite/gas/i386/property-5.d: Likewise.
	* testsuite/gas/i386/property-5.s: Likewise.
	* testsuite/gas/i386/x86-64-property-4.d: Likewise.
	* testsuite/gas/i386/x86-64-property-5.d: Likewise.
