i386: Allow only registers with VALID_INT_MODE_P modes in movstrict<mode> [PR93997]
*movstrict<mode>_1 insn pattern allows only general registers,
so we have to reject modes not suitable for general regs in
corresponding movstrict<mode> expander.
PR target/93997
* config/i386/i386.md (movstrict<mode>): Allow only
registers with VALID_INT_MODE_P modes.
testsuite/ChangeLog:
PR target/93997
* gcc.target/i386/pr93997.c: New test.
