[APX EGPR] Handle legacy insn that only support GPR16 (1/5)
These legacy insn in opcode map0/1 only support GPR16,
and do not have vex/evex counterpart, directly adjust constraints and
add gpr32 attr to patterns.
insn list:
1. xsave/xsave64, xrstor/xrstor64
2. xsaves/xsaves64, xrstors/xrstors64
3. xsavec/xsavec64
4. xsaveopt/xsaveopt64
5. fxsave64/fxrstor64
gcc/ChangeLog:
* config/i386/i386.md (<xsave>): Set attr gpr32 0 and constraint
jm.
(<xsave>_rex64): Likewise.
(<xrstor>_rex64): Likewise.
(<xrstor>64): Likewise.
(fxsave64): Likewise.
(fxstore64): Likewise.
gcc/testsuite/ChangeLog:
* lib/target-supports.exp: Add apxf check.
* gcc.target/i386/apx-legacy-insn-check-norex2.c: New test.
* gcc.target/i386/apx-legacy-insn-check-norex2-asm.c: New assembler test.
