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.

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

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)?

Anna Zaks 3e0f415d0d [analyzer] Remove the dependency on CheckerContext::getStmt() as well as the method itself.

Argyrios Kyrtzidis b8c3aaf479 Allow getting all source locations of selector identifiers in a ObjCMethodDecl.
Instead of always storing all source locations for the selector identifiers
we check whether all the identifiers are in a "standard" position; "standard" position is

  -Immediately before the arguments: -(id)first:(int)x second:(int)y;
  -With a space between the arguments: -(id)first: (int)x second: (int)y;
  -For nullary selectors, immediately before ';': -(void)release;

In such cases we infer the locations instead of storing them.

Anna Zaks c29bed3989 [analyzer] Refactor PathDiagnosticLocation: Make PathDiagnosticLocation(SourceLocation...) private. Most of the effort here goes to making BugReport refer to a PathDiagnosticLocation instead of FullSourceLocation.
(Another step closer to the goal of having Diagnostics which can recover from invalid SourceLocations.)

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 001fd5b498 Rename GRState to ProgramState, and cleanup some code formatting along the way.

Alexis Hunt 4a8ea1092a Modify some deleted function methods to better reflect reality:
- New isDefined() function checks for deletedness
 - isThisDeclarationADefinition checks for deletedness
 - New doesThisDeclarationHaveABody() does what
   isThisDeclarationADefinition() used to do
 - The IsDeleted bit is not propagated across redeclarations
 - isDeleted() now checks the canoncial declaration
 - New isDeletedAsWritten() does what it says on the tin.
 - isUserProvided() now correct (thanks Richard!)

This fixes the bug that we weren't catching

void foo() = delete;
void foo() {}

as being a redefinition.

Argyrios Kyrtzidis 2c49ec7f1d [analyzer] Migrate NSErrorChecker and DereferenceChecker to CheckerV2.
They cooperate in that NSErrorChecker listens for ImplicitNullDerefEvent events that
DereferenceChecker can dispatch.
ImplicitNullDerefEvent is when we dereferenced a location that may be null.

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.

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...).
