Subject: Provide a hook for the benefit of clients using clang IR gen as a
 subroutine: emit metadata associating allocas and global values with a Decl*.
  This feature is controlled by an option that (intentionally) cannot be
 enabled on the command line.

To use this feature, simply set
  CodeGenOptions.EmitDeclMetadata = true;
and then interpret the completely underspecified metadata. :)
