more confusing ifelse.

Use dotted names for if blocks (if.then vs ifthen).

Fix bug where the body block of an ObjCForCollectionStmt would not properly get expanded as a series of basic blocks.

 - Evaluation of , operator used bogus assumption that LHS could be
   evaluated as an integral expression even though its type is
   unspecified.

This change is making isICE very permissive of the LHS in non-evaluated 
contexts because it is not clear what predicate we would use to reject 
code here. The standard didn't offer me any guidance; opinions?

virtual registers possibly having multiple kills while still
being defined and killed in the same block. If LiveIntervals
is manually re-run after two-address lowering, it currently
does add extra kills to two-address instructions, but this
is considered a bug.

conversion functions. Instead, we just use a placeholder identifier
for these (e.g., "<constructor>") and override NamedDecl::getName() to
provide a human-readable name.

This is one potential solution to the problem; another solution would
be to replace the use of IdentifierInfo* in NamedDecl with a different
class that deals with identifiers better. I'm also prototyping that to
see how it compares, but this commit is better than what we had
previously.

special-purpose hook to a new pass. Also, add check to see if any
x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.

PreprocessorLexer now has a virtual method "IndirectLex" which allows it to call the lex method of its subclasses.  This is not for performance intensive operations.

Add Preprocessor::PushIncludeMacroStack() and Preprocessor::PopIncludeMacroStack(), two utility methods for manipulating the Preprocessor stack.  These will be used to remove manually manipulation of IncludeMacroStack from the rest of the Preprocessor implementation.

Move pieces of Lexer that the Preprocessor mutates to a new base class 'PreprocessorLexer'.  This will also be the base class of the new Preprocessed-Token-Header (PTH) lexer.  No functionality change.

Add (preliminary) transfer function support for ObjCForCollectionStmt.  Still need to flesh out some logic.

When processing DeclStmt, use the new interface to StateManager::BindDecl.  Conjuring of symbols is now done in VisitDeclStmt.

- Rename SetSVal to BindLoc
- Add BindDecl
- Add BindExpr

GRState:
- Environment now binds to Stmt* instead of Expr*.  This is needed for processing ObjCForCollectionStmt (essentially the declaration of the the 'element' variable can have an SVal attached to it).
- BindDecl no longer accepts Expr* for the initialization value; use SVal* instead.

llvm-svn: 59152

StoreManager::BindDecl now takes an SVal* for the initialization value instead of an Expr* (which can be null).  Lazy symbolication of conjured symbols is now the sole responsibility of GRExprEngine.
