74c51a0ff2 Generalize MaskedValueIsZero into a ComputeMaskedNonZeroBits function, which
is just as efficient as MVIZ and is also more general.

Fix a few minor bugs introduced in recent patches

3bedbd9d71 Make MaskedValueIsZero take a uint64_t instead of a ConstantIntegral as a
mask.  This allows the code to be simpler and more efficient.

Also, generalize some of the cases in MVIZ a bit, making it slightly more aggressive.

6dce1a7dfe Implement the beginnings of a facility for simplifying expressions based on
'demanded bits', inspired by Nate's work in the dag combiner.  This isn't
complete, but needs to unrelated instcombiner changes to continue.

8c9191c644 The interpreter assumes that the caller of runFunction() must be lli, and
therefore the function being called must be a main() returning an int.  The
consequences when these assumptions are false are not good, so don't assume
them.

interpretation has begun.  The JIT already handles this situation correctly, and
the interpreter can already handle new functions being added.
