Updated diff with latest changes:

1. Added FeatureAggressiveFMAFloat and FeatureAggressiveFMADouble in AArch64.td as micro-arch features.
2. Added EnableAggressiveFMA cl::opt in AArch64ISelLowering.cpp.
3. Implemented AArch64TargetLowering::enableAggressiveFMAFusion in terms of the changes from AArch64.td.
4. I would like the test in test/CodeGen/AArch64/fma-aggressive.ll to be included in this changeset, simply because the run-time test from https://reviews.llvm.org/D41810 has no way of determining whether or not AggressiveFMA was enabled, or not.
