First chunk of actual fast-isel selection code. This handles direct and indirect branches, as well as feeding compares for direct branches. PPCFastISel::PPCEmitIntExt() is just roughed in and will be expanded in a future patch. This also corrects a problem with selection for constant pool entries in JIT mode or with small code model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189202 91177308-0d34-0410-b5e6-96231b3b80d8
