    [PR102842] Consider all outputs in generation of matching reloads

    Without considering all output insn operands (not only processed
    before), in rare cases LRA can use the same hard register for
    different outputs of the insn on different assignment subpasses.  The
    patch fixes the problem.

    gcc/ChangeLog:

            PR rtl-optimization/102842
            * lra-constraints.c (match_reload): Ignore out in checking values
            of outs.
            (curr_insn_transform): Collect outputs before doing reloads of
operands.

    gcc/testsuite/ChangeLog:

            PR rtl-optimization/102842
            * g++.target/arm/pr102842.C: New test.
