Ted Kremenek 9d0bb1e366 Rename 'SValuator' to 'SValBuilder'. The new name
reflects what the class actually does.

John McCall e302792b61 GCC didn't care for my attempt at API compatibility, so brute-force everything
to the new constants.

Jordy Rose df28e8ec41 - Allow making ElementRegions with complex offsets (expressions or symbols) for the purpose of bounds-checking.
- Rewrite GRState::AssumeInBound to actually do that checking, and to use the normal constraint path.
- Remove ConstraintManager::AssumeInBound.
- Teach RegionStore and FlatStore to ignore those regions for now.

Jordy Rose 7f8ea4d677 Implicitly compare symbolic expressions to zero when they're being used as constraints. Part of PR7491.

Jordy Rose 79404afc1c When folding additive operations, convert the values to the same type. When assuming relationships, convert the integers to the same type as the symbol, at least for now.

Ted Kremenek d6b8708643 Split libAnalysis into two libraries: libAnalysis and libChecker.
(1) libAnalysis is a generic analysis library that can be used by
    Sema.  It defines the CFG, basic dataflow analysis primitives, and
    inexpensive flow-sensitive analyses (e.g. LiveVariables).

(2) libChecker contains the guts of the static analyzer, incuding the
    path-sensitive analysis engine and domain-specific checks.

Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.

This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker.  More changes pending.  :)

This change also exposed a layering violation between AnalysisContext
and MemRegion.  BlockInvocationContext shouldn't explicitly know about
BlockDataRegions.  For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet).  We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.
