Currently, if a warning references a cloned function, the name of the cloned
function will be emitted in the "In function 'xyz'" part of the diagnostic,
which users aren't supposed to see. This patch follows the DECL_ABSTRACT_ORIGIN
links until encountering the original function.

* langhooks.cc (lhd_decl_printable_name): Follow DECL_ABSTRACT_ORIGIN
links to the source

I would add a testcase but I'm not familiar with that process, and would need
some help. I also did not bootstrap or test this patch, I'm posting to see if
the CI will do it for me.
I used "while" because I'm not sure if there can be clones of clones or not.
The second check is because I see comments elsewhere that say:
"DECL_ABSTRACT_ORIGIN can point to itself", so I want to avoid a potential
infinite loop.
