2009-04-27add an abbreviation for common PARM_VAR_DECL. All but 9 of the Chris Lattner
parm var decls in leopard cocoa.h end up using this abbreviation, which shrinks the bitcode file by about 50K: 7217736->7167120.

2009-04-27Load most of the source manager's information lazily from the PCHDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70196 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-26Some fixes for PCH (de-)serialization of Objective-C AST nodes:Douglas Gregor
- Deal with the Receiver/ClassInfo shared storage in ObjCMessageExpr - Implement PCH support for ImplicitParamDecl - Fix the handling of the body of an ObjCMethodDecl - Several cast -> cast_or_null fixes - Make Selector::getIdentifierInfoForSlot work for 1-argument, NULL selectors. - Make Selector::getAsString() work with NULL selectors. - Fix the names of VisitObjCAtCatchStmt and VisitObjCAtFinallyStmt in the PCH reader and writer; these were never getting called. At this point, all of the pch-test tests pass for C and Objective-C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70163 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-26When writing a PCH file, write multiple type and declaration blocks asDouglas Gregor
necessary and iterate until all types and declarations have been written.
