John McCall 113bee0536 Remove BlockDeclRefExpr and introduce a bit on DeclRefExpr to
track whether the referenced declaration comes from an enclosing
local context.  I'm amenable to suggestions about the exact meaning
of this bit.

Dylan Noblesmith 2c1dd2716a Basic: import SmallString<> into clang namespace
(I was going to fix the TODO about DenseMap too, but
that would break self-host right now. See PR11922.)

Benjamin Kramer 4903802fbf Move a method from IdentifierTable.h out of line and remove the SmallString include.
Fix all the transitive include users.

Ted Kremenek 49b1e38e4b Change references to 'const ProgramState *' to typedef 'ProgramStateRef'.
At this point this is largely cosmetic, but it opens the door to replace
ProgramStateRef with a smart pointer that more eagerly acts in the role
of reclaiming unused ProgramState objects.

Ted Kremenek 632e3b7ee2 [analyzer] Make the entries in 'Environment' context-sensitive by making entries map from
(Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals.

This is needed to support basic IPA via inlining.  Without this, we cannot tell
if a Stmt* binding is part of the current analysis scope (StackFrameContext) or
part of a parent context.

This change introduces an uglification of the use of getSVal(), and thus takes
two steps forward and one step back.  There are also potential performance implications
of enlarging the Environment.  Both can be addressed going forward by refactoring the
APIs and optimizing the internal representation of Environment.  This patch
mainly introduces the functionality upon when we want to build upon (and clean up).

Anna Zaks c9abbe2b3e [analyzer] Add getLocationContext to CheckerContext
CheckerContext::getPredecessor is only used to get to the LocationContext
half of the times.

Anna Zaks f86615ca5c Static Analyzer Diagnostics: Kill the addVisitorCreator(callbackTy, void*) API in favor of addVisitor(BugReporterVisitor*).
1) Create a header file to expose the predefined visitors. And move the parent(BugReporterVisitor) there as well.

2) Remove the registerXXXVisitor functions - the Visitor constructors/getters can be used now to create the object. One exception is registerVarDeclsLastStore(), which registers more then one visitor, so make it static member of FindLastStoreBRVisitor.

3) Modify all the checkers to use the new API.

Anna Zaks 3a6bdf8f82 Remove EnhancedBugReport and RangedBugReport - pull all the extra functionality they provided into their parent BugReport. The only functional changes are: made getRanges() non const - it adds default range to Ranges if none are supplied, made getStmt() private, which was another FIXME.

Ted Kremenek f8cbac4b91 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.

John McCall c63de66c4f An insomniac stab at making block declarations list the variables they close
on, as well as more reliably limiting invalid references to locals from
nested scopes.

Ted Kremenek d99bd55a5e Chris Lattner has strong opinions about directory
layout.  :)

Rename the 'EntoSA' directories to 'StaticAnalyzer'.

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