[PATCH] First stage of call lowering for Mips fast-isel

[reed kotler]

Have cleaned up the executable test case a bit to make it convert to make check test better.

Am working on the make check test. So far no code bugs have been found in this abi testing.

I have a patch that fixes that with function attributes as in:

    static bool CC_Mips16RetHelper(unsigned ValNo, MVT ValVT,
                       MVT LocVT, CCValAssign::LocInfo LocInfo,
                       ISD::ArgFlagsTy ArgFlags, CCState &State)
    __attribute__((unused));
