Turn fail-stop errors into macaw translation failures
...
Previously, macaw-ppc (and macaw-arm) would call `error` if there were no
semantics available for a decoded instruction. This was useful during initial
development, but it is a problem for deployment. Now just turn missing
semantics into TranslationErrors, which appear as block terminators in macaw IR.
This will require more diligence in monitoring TranslationErrors for patterns
that need to be addressed.

[refinement] Provide list of forward path blocks to smt solving.
...
Currently smt solving just uses the first block of the first path,
which is not correct, but the framework for providing the list of
paths is now present.

[refinement] Invoke SMT solution at path-focused framework location.
...
The previous implementation invoked the SMT solver at the top level
for prototyping. This version moves the SMT solver invocation to the
intended location in the algorithm where the path is successively
extended and solutions are compared to identify the "best" refinement
solution.

CrucGen: Use SetStruct rather than making a new one from scratch

This means far fewer instructions (and hence fewer registers), and in
turn a lot less heap space. Peak memory usage is cut in half running
Brittle on a PPC64 exe with standard library.

[refinement] a function may have multiple paths to different exit points.
...
An "exit point" is a block which does not transfer to another block
within the function. An exit may be a RET or a JMP or an ite
representing different JMP targets; at this time it is assumed that
the latter cannot mix external and internal JMP targets.
