x86: Properly set YMM/ZMM features
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.
