Use chain_next on eh_landing_pad_d for GTY (PR middle-end/110510)

Browse source 
The backtrace in the bug report suggest there is a running out of
stack during GC collection, because of a long chain of eh_landing_pad_d.
This might fix that by adding chain_next onto eh_landing_pad_d's GTY marker.

OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
