until Doug Gregor's Type smart pointer code lands (or more discussion occurs).
These methods just call the new Type::getAs<XXX> methods, so we still have
reduced implementation redundancy. Having explicit getAsXXXType() methods makes
it easier to set breakpoints in the debugger.

Replaced Type::getAsLValueReferenceType(), Type::getAsRValueReferenceType(), Type::getAsMemberPointerType(), Type::getAsTagType(), and Type::getAsRecordType() with their Type::getAs<XXX> equivalents.

Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

Timings showed no significant difference before and after the commit.

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

  - Track implicit instantiations vs. the not-yet-supported explicit
  specializations
  - Give implicit instantiations of function templates (and member
  functions of class templates) linkonce_odr linkage.
  - Improve name mangling for function template specializations,
  including the template arguments of the instantiation and the return
  type of the function.

Note that our name-mangling is improved, but not correct: we still
don't mangle substitutions, although the manglings we produce can be
demangled.

'used' attribute on some of its meta-data. This results in two 
'llvm.used' arrays to be generated, and one of them is renamed to

A C++ member function always has either weak linkage (if it's inline or defined inline) or strong linkage (other cases).

It looks like codegen isn't emitting a call to the dtor in

get emitted.
