ppc: Change how we translate instructions represented by arch-specific statements
...
The old method involved providing the TH code a list of match expressions. This
made it very difficult to inspect arguments of instructions. The new approach
has the architecture backend provide a function that gets the first opportunity
to process instructions, which is much more flexible. This commit also includes
support for a number of cache hint instructions that use the new features.

[ppc] Fix an issue with floating point translation

The change is actually in the semantics (semmc), where we were extracting the

being simplified to zero, which manifest as unused fprc registers.

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.
