re PR debug/83084 (-fcompare-debug failure on ppc64le)

PR debug/83084
* valtrack.c (propagate_for_debug_subst, propagate_for_debug): Reset
debug insns if they would contain UNSPEC_VOLATILE or volatile asm.
(dead_debug_insert_temp): Likewise, but also ignore even non-volatile
asm.

* g++.dg/opt/pr83084.C: New test.
