Handle corner case where clang-cc is invoked directly to compile preprocessed source file without -main-file-name. In this case, CDDebugInfo is not able identify correct main source file becase SM.isFromMainFile() returns true for locations from header files as well as locations from main source file.
This patch takes conservative approach by not emitting more then one compile unit with isMain bit set.

This enables class recognition to work with PCH. I believe this means we can remove Sema::ObjCInterfaceDecls and it's usage within Sema::LookupName(). Will investigate.

the type assigned by sema (and is visible with sizeof(__func__) for
example) has nothing to do with what codegen ends up producing.
We should eventually add a method on PredefinedExpr to handle this.
In the meantime, just set up some framework and add some fixme's.

Add a CXXConstructExpr that represents an implicit call to a C++ constructor. I think CXXTemporaryObjectExpr is going to become a subclass of CXXConstructExpr, since CXXTemporaryObjectExpr represents a syntactic temporary, for example T()

in a bunch of declarations from the PCH file. We're down to loading

file needs to store. CodeGen needs to see these definitions (via
HandleTopLevelDecl), otherwise it won't be able to generate code for
them. 

This patch notifies the consumer (e.g., CodeGen) about function
definitions and variable definitions when the corresponding
declarations are deserialized. Hence, we don't eagerly deserialize the
declarations for every variable or function that has a definition in
the PCH file. This gives another 5% speedup for the Carbon-prefixed
"Hello, World!", and brings our PCH statistics down to something far
more reasonable:

*** PCH Statistics:
  13/20693 types read (0.062823%)
  17/59230 declarations read (0.028702%)
  54/44914 identifiers read (0.120230%)

PCH files now contain complete information about builtins, including
any declarations that have been synthesized as part of building the
PCH file. When using a PCH file, we do not initialize builtins at all;
when needed, they'll be found in the PCH file.

This optimization translations into a 9% speedup for "Hello, World!"
with Carbon.h as a prefix header and roughly a 5% speedup for 403.gcc
with its prefix header. We're also reading less of the PCH file for
"Hello, World!":
