    mips: Fix overaligned function arguments [PR109435]

    This patch changes alignment for typedef types when passed as
    arguments, making the alignment equal to the alignment of
    original (aliased) types.

    This change makes it impossible for a typedef type to have
    alignment that is less than its size.

    gcc/ChangeLog:

            PR target/109435
            * config/mips/mips.cc (mips_function_arg_alignment): Returns
            the alignment of function argument. In case of typedef type,
            it returns the aligment of the aliased type.
            (mips_function_arg_boundary): Relocated calculation of the
            aligment of function arguments.

    gcc/testsuite/ChangeLog:

            * gcc.target/mips/align-1-n64.c: New test.
            * gcc.target/mips/align-1-o32.c: New test.=
