Summary:
Currently the symbolic execution options, obtained from the command
line flags and preanalysis, are passed to the Control entry points as
a record, and then passed around within Control as needed. This diff
simplifies the code in Control by replacing the record mechanism with
an additional functor parameter containing the options. The main
benefit is that the bound option no longer needs to be part of the
analysis state.
This change does make the code in Sledge_cli slightly more
complicated, as it now performs a functor application using a
first-class module computed from the command line flags.

Summary:
Distinguish expressions that name globals from registers. This leads
to clearer code, and globals are semantically distinct from general
registers. In particular, they are constant, so any machinery for
handling assignment does not need to consider them. This diff only
adds the distinction to LLAIR, it is not pushed through to FOL, which
will come later.

Summary:
Distinguish expressions that name functions from registers. This leads
to clearer code, and function names are semantically distinct from
general registers. In particular, they are constant, so any machinery
for handling assignment does not need to consider them. Unlike general
globals, they never have initializer expressions, and in particular
not recursive initializers. This diff only adds the distinction to
LLAIR, it is not pushed through to FOL, which will come later.

Summary:
Refer to Llair modules using `Llair.` qualifier, except for in
`Frontend`, which makes so much use of `Llair` that it is now opened
(`Llair` only contains types and modules, so `open` is safe).
