Add location to clang classes created via reverse interop (#7533)

Browse Source 
The specific location's not ideal (rather than the open curly, or
semicolon for a declaration - the two locations should be the `class`
and then the class name), but the same as we do for functions for now &
enough to get by.

This specifically also fixes a crash I found due to dtors being
generated without a location (because implicitly created functions would
use the class's location), creating a function call without a debug
location, which fails the LLVM IR verifier.
