2156dfe383 (jump_optimize): Delete insns that set registers that are not used elsewhere. 
Fix some bugs in "if (...) x = a; else x = b;" code.
Remove uses of reorder_insns.
Add code to make scc insns for "if (...) x = exp;" if EXP is simple enough.
Optimize "if (...) x = b;" if jumps very expensive; don't use a REG as the
older value of X since it doesn't help and can hurt.
Correctly place generated insns in above case.

Likewise, when making new REG_DEAD notes for distribute_notes.

(distribute_notes): When placing second REG_DEAD or REG_UNUSED note or
ignoring such a note, update reg_n_deaths.

(simplify_comparison, case ASHIFT): Fix typo.

(try_combine): The insns made by a DEFINE_SPLIT might contain a PARALLEL and
the call to recog_for_combine might add it.


(combine_instructions): Clear significant_valid at end of combine pass for
a function.
(find_split_point, case MEM): See if first operand of the PLUS that makes
up an address is complex.

of an operator.

into arms by using known_cond.
If an arm is the first operand of the comparison, make it the true arm.

into logical operations.

them on the machine.
