as far as I can tell, and it fixes code like test/CodeGen/functions.c.

(Whatever performance effect it might have, crashing on a 
construct like this isn't really acceptable; I've run into this 
multiple times.)

Added -g command line options to clang for generating source level debug information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo.

reimplemented in Sema someday.  This is tracked in PR2236.  Until then
disabling it removes some bogus diagnostics (see 2236).

Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

remaining open issues I've communicated to him:

1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
   all parent class ivars) and flattens classes.  If A derives from B, 
   and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

David, please review.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

we emit stuff like this:

abort on missing sema of initializers, now
we emit stuff like this:

t3.c:1:24: warning: cannot codegen this initializer yet

                       ^~~~~~~~~~~~~~~~~~~~~~~~

This should be removed when sema is finished.
