FAST-ISEL should fall back to DAG-ISEL when a global variable has the toc-data attribute. A number of the 64-bit checks were 
duplicated in the lit test because of

1. Slightly different output between -O0 and -O2 due to FAST-ISEL vs DAG-ISEL codegen.
2. In preperation of a peephole optimization that will run when optimizations are enabled.

Also updates where we dump the mir since the `ppc-ctr-loops-verify` pass happens at a different time in the pipeline at -O0 when generating 32-bit code. I
