5144fe2287 Because of a lack of a clear ownership role between ObjCInterfaceDecls and 
ObjCPropertyDecls, have TranslationUnit destroy ObjCPropertyDecls. This is a
horrible hack, and must be removed eventually.

09a0d04ea0 Initial work on additional memory collection for ObjC AST objects. We now 
have Destroy methods of ObjcMethodDecl and ObjCInterfaceDecl which recursively
destroy their owned Decls and Stmts.  There are a few cases where it is not
clear what to do (FIXMEs included in the patch).

f1123e58fc Tighten up the abstraction slightly.

13237ac3b9 Wrap MVT::ValueType in a struct to get type safety 
and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).

25449a5221 Fix <rdar://problem/5986833> clang on xcode: incompatible type returning 'void', expected 'int'. 
- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.

1247c07742 As comments said, for negative value, the arithmetic 
over-shift-right should return -1. So here it should be signed-extended,
when bitwidth larger than 64.
