Ted Kremenek 48b430d789 Fix an insidious bug in BugReporter where
a node in the trimmed graph might not always
correctly map back to the original error node.
This could cause a crash in some cases when
flagging memory leaks.

Ted Kremenek b3b56c6bcd Adjust method calls to reflect name changes in
ImmutableSet/ImmtuableMap/ImmutableList APIs.

Along the way, clean up some method names in
the static analyzer so that they are more
descriptive and/or start with lowercase letters.

Tom Care 58191966bc Refactored BugReporter to refer to EndNode as ErrorNode. We currently make the assumption that EndNode == ErrorNode, but upcoming changes will break this.

Zhongxing Xu 2cd7a78c76 Introduce new CFGElement hierarchy to support C++ CFG, based on Marcin's patch
and discussions with Ted and Jordy.

Ted Kremenek ff3a4ff6e9 Use FindReportInEquivalenceClass to identify all the nodes used for the trimmed graph (in BugReporter). This fixes a problem where a leak that happened to occur on both an exit() path and a non-exit() path was getting reported with the exit() path (which users don't care about).
This fixes:

<rdar://problem/8331641> leak reports should not show paths that end with exit() (but ones that don't end with exit())

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

Argyrios Kyrtzidis 568bc84562 Remove Decl::getCompoundBody().
This has 2 (slight) advantages:
-Make explicit at getBody()'s callsite that we expect/handle only CompoundStmt and not CXXTryStmt.
-Better tracking of Decl::getBody()'s callsites.

Benjamin Kramer b11416d061 Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream.
The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

Zhongxing Xu 0f290ec0f0 Fix PR 6725. It looks like the copy constructor gets elided during inlining.
This bug only shows up with GCC 4.4.1 Release-Asserts build.

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.
