[PR118067][LRA]: Check secondary memory mode for the reg class
This is the second patch for the PR for the new test. The patch
solves problem in the case when secondary memory mode (SImode in the
PR test) returned by hook secondary_memory_needed_mode can not be used
for reg class (ALL_MASK_REGS) involved in secondary memory moves. The
patch uses reg mode instead of one returned by
secondary_memory_needed_mode in this case.
gcc/ChangeLog:
PR rtl-optimization/118067
* lra-constraints.cc (invalid_mode_reg_p): New function.
(curr_insn_transform): Use it to check mode returned by target
secondary_memory_needed_mode.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr118067-2.c: New.
