Change the fast-isel-abort option from bool to int to enable "levels" Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

[PowerPC] Add fast-isel branch and compare selection. 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. llvm-svn: 189202
