For -feliminate-dwarf2-dups the problem with PCH is that it wipes
unconditionally the DW_TAG_GNU_BINCL DIE (or, if -feliminate-dwarf2-dups was
used for PCH replaces or adds it with a wrong filename), resulting in inbalance
between the notes.
I guess the easiest would be just disable PCH for -feliminate-dwarf2-dups
(reject writing a PCH file with that option, and c_common_no_more_pch with it
too).
