[google]: initialize language field for clone function struct

[Xinliang David Li]

During function cloning, the language field of the src func is not
copied. This can lead to null dereference when gcc calls into langhook
functions.  Unfortunately, I lost track of the test case.

Ok for trunk ?

Thanks,

David
