rtl-optimization/119689 - compare-debug failure with LRA

The previous change to fix LRA rematerialization broke compare-debug
for i586 bootstrap.  Fixed by using prev_nonnote_nondebug_insn
instead of prev_nonnote_insn.

PR rtl-optimization/119689
PR rtl-optimization/115568
* lra-remat.cc (create_cands): Use prev_nonnote_nondebug_insn
to check whether insn2 is directly before insn.

* g++.target/i386/pr119689.C: New testcase.

(cherry picked from commit 088887de7717a22b1503760e9b79dfbe22a0f428)
