PR target/69442
* combine.c (combine_instructions): For REG_EQUAL note with
SET_DEST being ZERO_EXTRACT, also temporarily set SET_DEST
to the underlying register.
* doc/rtl.texi (REG_EQUAL): Document the behavior of
REG_EQUAL/REG_EQUIV notes if SET_DEST is ZERO_EXTRACT.
* gcc.dg/pr69442.c: New test.
