[PATCH] D35180: Expose the Clang::QualType to llvm::Type conversion functions

[Benoit Vey via Phabricator via cfe-commits]

Praetonus created this revision.

This change exposes the various CodeGenTypes::ConvertType functions in the 
public Clang API. This allows external tools using the Clang API to rely on it 
to generate LLVM types from C types. The precise use case that motivated this 
change is explained in an email 
<https://lists.llvm.org/pipermail/cfe-dev/2017-July/054550.html> to the Clang 
mailing list.
