Revert "Disable codegen prepare critical edge splitting. Machine instruction passes now"
...
This reverts revision 114633. It was breaking llvm-gcc-i386-linux-selfhost.
It seems there is a downstream bug that is exposed by
-cgp-critical-edge-splitting=0. When that bug is fixed, this patch can go back
in.
Note that the changes to tailcallfp2.ll are not reverted. They were good are
required.

...
extract_subreg / insert_subreg, etc.
- Add support for more aggressive insert_subreg coalescing.
