    middle-end/113622 - handle store with variable index to register

    The following implements storing to a non-MEM_P with a variable
    offset.  We usually avoid this by forcing expansion to memory but
    this doesn't work for hard register variables.  The solution is
    to spill and operate on the stack.

            PR middle-end/113622
            * expr.cc (expand_assignment): Spill hard registers if
            we index them with a variable offset.

            * gcc.target/i386/pr113622-2.c: New testcase.
            * gcc.target/i386/pr113622-3.c: Likewise.=
