Ted Kremenek a98358ea13 [analyzer] ObjC message sends to nil receivers that return structs are now okay (compiler zeroes out the data). Fixes <rdar://problem/9151319>.

Anna Zaks da4c8d6811 [analyzer] Rename generateNode -> addTransition in CheckerContext
Also document addTransition methods.

Anna Zaks b473816b4a [analyzer] Simplify CheckerContext
Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition.
Remove addTransition method since it's the same as generateNode. Maybe we should
rename generateNode to genTransition (since a transition is always automatically
generated)?

Benjamin Kramer b89514a9b8 Change operator<< for raw_ostream and NamedDecl to take a reference instead of a pointer.
Passing a pointer was a bad idea as it collides with the overload for void*.

Jordy Rose 087611ed81 [analyzer] Remove TransferFuncs.h, then deal with the fallout.
And with that, TransferFuncs is gone!

Douglas Gregor e8bbc12152 Extend the ASTContext constructor to delay the initialization of
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

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 5ef32dbf2a Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at.

Ted Kremenek 8df44b2632 [analyzer] Introduce new MemRegion, "TypedValueRegion", so that we can separate TypedRegions that implement getValueType() from those that don't.

Chris Lattner 0e62c1cc0b remove unneeded llvm:: namespace qualifiers on some core types now that LLVM.h imports
them into the clang namespace.

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.

Argyrios Kyrtzidis ffb08c46fa [analyzer] Handle the dot syntax for properties in the ExprEngine.
We translate property accesses to obj-c messages by simulating "loads" or "stores" to properties
using a pseudo-location SVal kind (ObjCPropRef).

Checkers can now reason about obj-c messages for both explicit message expressions and implicit
messages due to property accesses.

Argyrios Kyrtzidis 37ab726d63 [analyzer] Introduce ObjCMessage which represents both explicit ObjC message expressions and implicit
messages that are sent for handling properties in dot syntax.

Replace all direct uses of ObjCMessageExpr in the checkers and checker interface with ObjCMessage.

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...).
