[PATCH] Decouple creation of CodeGenTypes from CodeGenModule.

[Mark Lacey]

Hi -

Please review and let me know if you have any feedback.

Thanks,

Mark

Currently the only way to create a CodeGenTypes class is to pass it a
CodeGenModule, which is primarily used to initialize the members of
CodeGenTypes, but is also used in a couple of places to gain access to a
few members of CodeGenModule (OpenCLRuntime, DebugInfo,
and TargetCodeGenInfo).

This change makes it possible to construct a CodeGenTypes class
independently of a CodeGenModule. The constructor to CodeGenTypes is
updated to explicitly have parameters for each of its members, and new
pointer members are added for the information that was being referenced
from CodeGenModule.
