    PR target/106877: Robustify reg-stack to malformed asm.

    This patch resolves PR target/106877 an ICE-on-invalid inline-asm
    regression.  An innocent upstream change means that the test case
    from PR inline-asm/84683 now hits a different assert in reg-stack.cc's
    move_for_stack_reg.  Fixed by duplicating Jakub's solution to PR 84683
    https://gcc.gnu.org/pipermail/gcc-patches/2018-March/495193.html at
    this second (similar) gcc_assert.
