    [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.
