Summary:
Change `-llair-output` to `-output`, for binary form, and
`-llair-txt-output` to `-llair-output`, for textual form. Also
correspondingly change `.llair` to `.bllair`, for binary, and
`.llair.txt` to `.llair` for text.
This improves command line argument completion, and makes `.llair` the
extension of the files most commonly interacted with.

Summary:
Add a Report.status type to represent the overall status of an
analysis run, and revise handling of backtraces to preserve the trace

Summary:
The SLEdge internal first-order theory solver targets the "word
problem", where a query has the form `C ⊢ L` where `C` is a
conjunction of literals and `L` is a single literal. This can be
abused to implement a naive SMT solver using an expansion to
disjunctive-normal form and checking `C ⊢ false` for each branch `C`
of the DNF. This is not useful as an SMT solver, but can be used for
testing.

Summary:
Generate output on stderr containing lines such as:
```
solve_for_vars time: 0.105 ms 0.871 ms 79 calls
```
which indicates that the current maximal time of a single
`solve_for_vars` query is `0.105 ms` and so far the total time spent in
`solve_for_vars` over `79` queries is `0.871 ms`.
At program exit, there is also a line for each timer indicating the
max query time and final accumulated duration and number of queries:
```
solve_for_vars time: 0.173 ms 17.242 ms 1108 calls
```
Additionally, replay sexp are dumped interactively. A query exceeding
1 sec is dumped, then one exceeding 2 sec, then 4 sec, etc.

The frontend translation of exceptional control flow is untrusted

Summary:
By default all functions except those specified as entry points in the
config file are "internalized". Internal functions are removed if they
are not called. It is sometimes necessary to disable internalization,
e.g. to analyze the llvm tests.

Sometimes the models for the C/C++ runtime and standard libraries are
not needed. Furthermore, sometimes, e.g. when analyzing llvm tests,
trying to link them fails.

Summary:
This diff adds a "-prenalyze-globals" flag to all analyze targets
which, when set, computes used-globals sets for all reachable
functions and then uses that information to track only relevant
global variables at calls in the main analysis.

Summary:
Adds an abstract domain to track global variable usages, as well as supporting
changes to the frontend, IR and CLI. This analysis will support optimizations
to the main symbolic-heap analysis, but for now can be invoked independently
through the `-domain` flag on `analyze` targets of the Sledge executable.

Outputting the list of bitcode inputs when no output flag is ok for
