[fast-isel] Address Eli's comments for r152847. Specifically, add a test case
...
and still allow immediate encoding, just not with cmn.

ARM VLDR/VSTR instructions don't need a size suffix.
...
Canonicallize on the non-suffixed form, but continue to accept assembly that
has any correctly sized type suffix.

Add support for encoding immediates in icmp and fcmp. Hopefully, this will
...
remove a fair number of unnecessary materialized constants.
