simplify and comment some code better. Make BindRuntimeGlobals
more optimistic that it will work (optimizing for the common case).

random code cleanups.

llvm-svn: 67437

remove obviously dead code: you can't bitcast a pointer to "Ty" (a function type).

llvm-svn: 67436

avoid making constant folding logic eliminate obviously dead bitcasts, speeding up PR3810
by ~2%.

llvm-svn: 67434

Add a fast path to CodeGenModule::getMangledName for almost all C functions,
speeding up the testcase in PR3810 by 60%.

IRgen support for alias of global variable.
- PR3818.

objc: Implemented variables declared in class interface

Adjust for linkage name change.

llvm-svn: 66691

Correct for change of this name in LLVM.

Backout r66408, we don't want handling of globals to rely on the
module symbol table. The root problem inspiring this was fixed in
r66316 (and again in r66506).

Be sure to never create two functions with the same name, instead arrange to
reuse the prior one.

llvm-svn: 66408

Make constant emission for @encode use the common string emission code.
This is a bit cleaner, and also "fixes" bad code that compares the
addresses of the string constants.

llvm-svn: 66346

Fixup our uses of various linkages to match how llvm now works. I think they are all
correct, but an extra set of ObjC eyes would be good.

IRgen support for weak_import.

Don't mangle names of local variables.
- 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.

Make IRGen compatible with declaring a function with incomplete
return/argument types. (The generated IR isn't ideal, but we can't
really do better in general.)

Fix PR3612. We ensure that we add builtins to the GlobalDeclMap and
we ensure that things added to the module can be found even when they

same module.
