Revert:
[PR106746] drop cselib addr lookup in debug insn mem
The testcase used to get scheduled differently depending on the
presence of debug insns with MEMs. It's not clear to me why those
MEMs affected scheduling, but the cselib pre-canonicalization of the
MEM address is not used at all when analyzing debug insns, so the
memory allocation and lookup are pure waste. Somehow, avoiding that
waste fixes the problem, or makes it go latent.

A recent change only initializes the regs.how[] during Dwarf unwinding
which resulted in an uninitialized offset used in return address signing
and random failures during unwinding. The fix is to encode the return
address signing state in REG_UNSAVED and REG_UNDEFINED.
