Be more lenient when interpreting bogus expressions.
...
Previously we were asserting that some bogus-y things don't happen.
Unfortunately, these expressions can occur in code that was not
directly written by the user (e.g., comparisons for setting various
machine flags). To allow for that, we allow the expressions, but
give them undefined values. So the proof will succeed only if it
does not depend on the values of these bogus comparisons.

Add some support for function calls.
...
We basically punt, by passing-in a function to use as the implementation of
all functions. This function is supposed to look at the IP, and
decide what to do.
