MallocChecker creates implicit dependencies between checkers and needs to be handled differently.

Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.

This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

Rename the 'EntoSA' directories to 'StaticAnalyzer'.

Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).

(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.

Split CodeTextRegion into FunctionTextRegion and BlockTextRegion.  This a precursor to having basic static analysis support for blocks.

PthreadLockChecker doesn't need PreVisitCallExpr() yet.  All the current logic should be done in PostVisitCallExpr()

llvm-svn: 86959

Add most of the boilerplate logic for a simple pthread_mutux_lock() -> pthread_mutex_unlock() checker.  We need to add a visitor method to Checker for handling dead symbols in order to detect locks that are not unlocked.
