re PR rtl-optimization/85342 (ICE: SIGSEGV in copyprop_hardreg_forward_1 (regcprop.c:995) with -O2 -mavx512vl)

PR rtl-optimization/85342
* regcprop.c (copyprop_hardreg_forward_1): Remove replaced array, use
a bool scalar var inside of the loop instead.  Don't try to update
recog_data.operand after failed apply_change_group.

* gcc.target/i386/pr85342.c: New test.
