PR rtl-optimization/41511
* combine.c (record_value_for_reg): Pass explicit values as argument
to get_last_value_validate.
(get_last_value_validate): Document INSN parameter.
For non-readonly MEMs, assume they might have been modified if INSN
was in another basic block.
(get_last_value): Minor reformatting.
