    middle-end/104786 - ICE with asm and VLA

    The following fixes an ICE observed with a MEM_REF allows_mem asm
    operand referencing a VLA.  The following makes sure to not attempt
    to go the temporary creation way when we cannot.

            * cfgexpand.c (expand_asm_stmt): Do not generate a copy
            for VLAs without an upper size bound.

            * gcc.dg/pr104786.c: New testcase.
