turn on memset idiom recognition by default. Though there are still lots of
...
limitations, this kicks in dozens of times in the 4 specfp2000 benchmarks,
and hundreds of times in the int part. It also kicks in hundreds of times
in multisource.
This kicks in right before loop deletion, which has the pleasant effect of
deleting loops that *just* do a memset.

Fix a README item by having InstructionSimplify do a mild form of value
...
numbering, in which it considers (for example) "%a = add i32 %x, %y" and
"%b = add i32 %x, %y" to be equal because the operands are equal and the
result of the instructions only depends on the values of the operands.
This has almost no effect (it removes 4 instructions from gcc-as-one-file),
and perhaps slows down compilation: I measured a 0.4% slowdown on the large
gcc-as-one-file testcase, but it wasn't statistically significant.
