Ted Kremenek 49936f76ec CFG: 'WhileStmts' needs an extra block to indicate the "loop back" path.

Mike Stump 6ea352a750 We avoid the count of diagnostics when not generating carent 
diagnostics to improve gcc compatibility; useful for dejagnu testing.

Ted Kremenek 902393b4b7 CFG: 
- Add 'LoopTarget' pointer field to CFGBlock. This records if the block is used
  as the 'loop back' path back to the head of a loop.
- For ForStmt, encode the loop back target as the increment code.

Eli Friedman 5d72d41189 Get rid of some useless uses of NoExtensions. The philosophy here is 
that if we're going to print an extension warning anyway, 
there's no point to changing behavior based on NoExtensions: it will 
only make error recovery worse.

Note that this doesn't cause any behavior change because NoExtensions 
isn't used by the current front-end.  I'm still considering what to do about
the remaining use of NoExtensions in IdentifierTable.cpp.

Douglas Gregor 7b71e63120 Add a header containing the Clang version; make the driver use this 
Clang version value rather than hard-coding "1.0".

Add PCH and Clang version information into the PCH file. Reject PCH
files with the wrong version information.

Chris Lattner 8575daaa82 Teach PCH that ASTContext is optional. Move -parse-noop and -Eonly (so far) 
processing to after PCH is loaded.  -Eonly and -parse-noop are close to working
with PCH now but are not quite there yet.

Douglas Gregor 61cac2b295 Add Sema::ExtVectorDecls and Sema::ObjCCategoryImpls to the PCH file. Since these vectors are very, very rarely used and, when used in headers, and even when used are relatively small, we load them eagerly.

Ted Kremenek ebbef7d0d3 Add new checker-specific attribute 'objc_ownership_cfretain'. This is the same 
as 'objc_ownership_cfretain' except that the method acts like a CFRetain instead
of a [... retain] (important in GC modes). Checker support is wired up, but
currently only for Objective-C message expressions (not function calls).

Chris Lattner eeb0569b5a encode the type and decl offsets with 32-bits for entry instead

Chris Lattner 258172e78d add an abbreviation for common PARM_VAR_DECL. All but 9 of the

Douglas Gregor 258ae54a5d Load most of the source manager's information lazily from the PCH 
file. In particular, only eagerly load source location entries for
files and for the predefines buffer. Other buffers and
macro-instantiation source location entries are loaded lazily.

With the Cocoa-prefixed "Hello, World", we only load 815/26555 source
location entities. This halves the amount of user time we spend in
this "Hello, World" program with -fsyntax-only (down to .007s).

This optimization is part 1 of 2 for the source manager. This
eliminates most of the user time in loading a PCH file. We still spend
too much time initialize File structures (especially in the calls to
stat), so we need to either make the loading of source location
entries for files lazy or import the stat cache from the PTH
implementation.
