>> 1) r243485: [mips][FastISel] Fix call lowering by bailing out on "fastcc" calls.

>> 3) [mips][FastISel] Apply only zero-extension to constants prior to their materialization. (http://reviews.llvm.org/D11592 pending LGTM from Daniel)

>> We are able to bootstrap Clang with FastISel and pass every test from the LLVM test-suite under various and different configurations. Although, we are almost at the end of the RC2 phase, these patches have been tested thoroughly throughout the last 2+ weeks and it would be nice to consider them for the RC branch. I've CC'ed Daniel Sanders if you have any question or need clarification about something.
