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).

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).
