Fix a TH bug

Extend the uninterpreted function evaluator
...
It is currently very messy because the ppc.is_r0 function breaks some
abstraction boundaries that make it very irregular. There is some common code
that can probably be factored out, but it will still be a mess.
The other big change is handling the read_mem calls.

Add support for a number of new uninterpreted functions
...
This covers evaluating all of the statically-evaluated functions in expression
contexts (e.g., is_r0 and the memory reference extraction functions).
The expansion seems pretty reasonable.
There are still some cases to handle w.r.t. floating point elementary functions
and memory reads and writes, which need to be handled a bit differently.
Note: we also have to call the formula simplifier soon.

[ppc] Add a helper for turning operands into bitvectors

The main function is 'extractValue', which takes an operand and returns a macaw
bitvector for it (in the PPCGenerator monad).
There are still some missing cases for the memory operands.

Plumb through most of the TH bits to generate 'execInstruction'
...
The remaining part is 'genCaseBody', which is where we'll write the translator
from ParameterizedFormula to TH Exps. The semantics are loaded from semmc and
the outer case expression breaking down instructions is all in place. This has
several accompanying changes in semmc and dismantle.
