3ee25dca5b Add a break statement that I accidentally deleted when
I shuffled the fast-isel command-line options around. This fixes
a bunch of fast-isel failures.

aeb5c7b353 Implement "visitPow". This is mainly used to see if we have a pow() call of this
form:

          powf(10.0f, x);

If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

4344a5d0d7 Change -fast-isel-no-abort to -fast-isel-abort, which now defaults
to being off by default. Also, add assertion checks to check that
the various fast-isel-related command-line options are only used
when -fast-isel itself is enabled.

9a0d1ba051 Revert my previous change -- the subtraction of two constants was a no-op
before. This is taken care of in the selection DAG pass. In my opinion, this
should be in one place or the other. I.e., it should probably be removed from
the DAG combiner (along with the other arithmetic transformations on constants
that are essentially no-ops).
