This refactors demand analysis so we export assignment inferred values
and also no longer compute demands for assigments when inference
infers a value for them.
This exposes more information but requires changes to consumers of
information.
* Update macaw-x86-tests to build properly.
* Fix off by two error in memMapOverwrite
* Introduce some special handling for unsigned-extension in stack
analysis so it knows one value is the unsigned extension of another.
* Error report formating improvements
* Slightly more precise treatment of archfn is bound updates.
Consolidate three different checks that control when to explore
a function into a single one defined in exploreFunPred.
Modify noreturn function calls to not treat the return address
as a potential function entry point.
Add basic checking of LSDA address to compare-dwarfdump.
Minor code refactoring and submodule updates.
* update to bv-sized branch of what4 and other things
* removed parameterized-utils submodule completely
* Updates submodules
* Fixes macaw-symbolic w.r.t. crucible-llvm changes

These packages replace the old macaw-arm (which has been removed). The only
change to the core macaw is to introduce a `Lift` instance for the Endianness
data type, which is used in macaw-semmc.
The macaw-aarch32 package uses the official ARM semantics (via the
asl-translator package). In its current state, macaw-aarch32 seems to handle
the common idioms of simple ARM binaries. Position independent executables have
not been tested yet. The semantics and disassemblers for Thumb are present, but
not integrated into code discovery at this time. There are some tests in
macaw-aarch32. Compile times are longer than necessarily desired.
macaw-aarch32 can be compiled in two modes: lite mode (cabal flag -fasl-lite),
which uses a restricted set of instructions for testing, and takes less time to
compile. The full instruction set is the default, though there are a few
undefined functions that are not yet handled for the full set, mostly relating
to floating point operations.
The macaw-aarch32-symbolic package is currently a stub, but is implemented to
provide a few necessary instances.
