Yet another chunk of fast-isel code. This one handles various conversions involving floating-point. (It also includes some miscellaneous handling throughout the back end for LWA_32 and LWAX_32 that should have been part of the load-store patch.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189677 91177308-0d34-0410-b5e6-96231b3b80d8
