    Add flags to control memcpy and memset inlining

    This adds -fmax-inline-memcpy-insns and -fmax-inline-memset-insns.
    These flags control when we inline calls to memcpy/memset with
    statically known arguments. The flag naming style is taken from GCC
    and the same limit is used by both GCC and LLVM.
