* jump.c (delete_prior_computation): New function, broken
out of delete_computation. Check for side effects with
side_effects_p instead of FIND_REG_INC_NOTE. Handle
multi-word hard registers.
(delete_computation): Use it. Check for side effects with
side_effects_p instead of FIND_REG_INC_NOTE. Synthesize a
missing REG_DEAD note for a register which is both set and
used by an insn.

* tree.c (cp_build_qualified_type_real): Handle
pointer-to-member-function types correctly.

for weak symbols.
