LLVM Weekly - #45, Nov 10th 2014

* The MIPS backend has reached a milestone in support for the N32/N64 ABI.
This commit fixes all known bugs for this ABI and the first 10000 tests
generated by ABITest.py pass. [r221534](http://reviews.llvm.org/rL221534).

I accidentally broke sret arguments in this commit but this should be fixed in r221604.
