re PR debug/80025 (ICE w/ -O2 (-O3, -Ofast) -g -ftracer (infinite recursion in rtx_equal_for_cselib_1))
PR debug/80025
* cselib.h (rtx_equal_for_cselib_1): Add depth argument.
(rtx_equal_for_cselib_p): Pass 0 to it.
* cselib.c (cselib_hasher::equal): Likewise.
(rtx_equal_for_cselib_1): Add depth argument. If depth
is 128, don't look up VALUE locs and punt. Increment
depth in recursive calls when walking VALUE locs.
* gcc.dg/torture/pr80025.c: New test.
