5661 patterns using reg_before_reload_operand predicate.
5662 * config/pa/predicates.md (reg_before_reload_operand): Tighten
5663 predicate to reject register index and LO_SUM DLT memory forms
5664 after reload.

5691 (BUILT_IN_TSAN_WRITE_RANGE): New built-in function.
5692 * tsan.c (instrument_expr): Handle COMPONENT_REF and BIT_FIELD_REF.
5693 Use BUILT_IN_TSAN_READ_RANGE and BUILT_IN_TSAN_WRITE_RANGE for
5694 unaligned memory regions.
