Initialize and end alias analysis.
(nonlocal_mentioned_p): Rename from nonlocal_reference_p.

field in reg_equiv.
(memref_referenced_p): Likewise.

allow it to be moved out of a loop. Update
REG_DEAD notes when substituting into an insn.

already error_mark_node.
From-SVN: r36955
* haifa-sched.c (compute_trg_info): Add explanatory comments.
New local update_blocks. Use update_blocks to remove duplicates
when computing update blocks. Check for bblst_table overflow.
