[x86_symbolic] Use stable value for generating x86 register name.
Relying on the underlying Show instance representation for the
register name is more brittle, especially if the Show becomes a
structural representation (e.g. "X86_GP 14") that introduces spaces
and other elements that can cause problems.  Generate the register
name in a more reliable manner for the symbolic variable use case
here.

5a8fba6d08 Cache TypeRepr and Position values
Generating the type of the register structure on demand was causing
`TypeRepr` to be the biggest chunk of the heap.  Similarly, we only need
to create a new `Position` when we change the offset.

cc85cfe657 Clean up and document the macaw-symbolic API
This cleanup consolidates the interface to macaw symbolic into two (and a half)
modules:

 - Data.Macaw.Symbolic for clients who just need to symbolically simulate
   machine code
 - Data.Macaw.Symbolic.Backend for clients that need to implement new
   architectures
 - Data.Macaw.Symbolic.Memory provides a reusable example implementation of
   machine pointer to LLVM memory model pointer mapping

Most functions are now documented and are grouped by use case.  There are two
worked (compiling) examples in the haddocks that show how to translate Macaw
into Crucible and then symbolically simulate the results (including setting up
all aspects of Crucible).  The examples are included in the symbolic/examples
directory and can be loaded with GHCi to type check them.

The Data.Macaw.Symbolic.Memory module still needs a worked example.

There were very few changes to actual code as part of this overhaul, but there
are a few places where complicated functions were hidden behind newtypes, as
users never need to construct the values themselves (e.g., MacawArchEvalFn and
MacawSymbolicArchFunctions).  There was also a slight consolidation of
constraint synonyms to reduce duplication.  All callers will have to be updated.

There is also now a README for macaw-symbolic that explains its purpose and
includes pointers to the new haddocks.

This commit also fixes up the (minor) breakage in the macaw-x86-symbolic
implementation from the API changes.

Fix warnings in macaw-base; Fix errors in macaw-symbolic.

type-class constraints in CrucGen.hs which propagated to other changes.
