GetAddrOfFunction.  This is simpler and more efficient.

CreateFunctionPrototypeIR, though my next patch will eliminate
it entirely.

1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

This is a bit cleaner, and also "fixes" bad code that compares the 
addresses of the string constants.

CodeGenModule::CreateRuntimeVariable.

 - No real functionality change; although we now assert on silly
   things like:
--
int objc_exception_throw;
void f0() { @throw(@"A"); }
--
   instead of accepting it.

 - <rdar://problem/6652110> clang should support weak_import

 - For one thing, this adds unneeded overhead; for another, this
   routine can be used to emit unnamed decls which we shouldn't try to
   mangle.

really do better in general.)

BlockModule.  No functionality change.  This should help people that
don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks

we ensure that things added to the module can be found even when they
are not in GlobalDeclMap.  The later is for increased flexibility,
should someone want to do something tricky like extern "Ada" in the
same module.

The big difference here is that (like string literal) @encode has

   or more elegant solution yet.
