x86: Allow 32-bit registers for tpause and umwait
Since only the first 32 bits of input operand are used for tpause and
umwait, the REX.W bit is skipped. Both 32-bit registers and 64-bit
registers are allowed.
gas/
* testsuite/gas/i386/x86-64-waitpkg.s: Add 32-bit registers
tests for tpause and umwait.
* testsuite/gas/i386/x86-64-waitpkg-intel.d: Updated.
* testsuite/gas/i386/x86-64-waitpkg.d: Likewise.
opcodes/
* i386-dis.c (prefix_table): Replace Em with Edq on tpause and
umwait.
* i386-opc.tbl: Allow 32-bit registers for tpause and umwait in
64-bit mode.
* i386-tbl.h: Regenerated.
