    [RA]: Fixing LRA cycling for multi-reg variable containing a fixed reg

    PR111971 test case uses a multi-reg variable containing a fixed reg.  LRA
    rejects such multi-reg because of this when matching the constraint for
    an asm insn.  The rejection results in LRA cycling.  The patch fixes this
issue.

    gcc/ChangeLog:

            PR rtl-optimization/111971
            * lra-constraints.cc: (process_alt_operands): Don't check start
            hard regs for regs originated from register variables.

    gcc/testsuite/ChangeLog:

            PR rtl-optimization/111971
            * gcc.target/powerpc/pr111971.c: New test.
