[PATCH] Add basic conditional branches in mips fast-isel

[reed kotler]

1. Add comment making clear the how the code for the basic branch is working. This particular part was copied from the PPC port but we will expand this soon to do more cases by porting the AARCH64 version of this routine.

2. Add a FIXME to try and eliminate some unneeded code. This frequently happens in fast-isel because it's  a simple one pass compiler.
