integral conversion to word or narrower.
(fold, case NOP_EXPR): Ignore conversion to same type as operand.
(fold, case COND_EXPR): Make third operand the simplest.

(store_expr): If don't want a value and storing into promoted
variable, do conversion at tree level; don't copy volatile MEM unless
want value, as comment says.

(find_basic_blocks): Call it to physically delete insns in
unreachable blocks.  When scanning blocks after dead ones,
start scanning after the dead one (not at the dead one).
If there are lots of unreachable blocks, make another pass to squeeze
them out (this reduces memory usage in some pathalogical cases by a
significant amount without resorting to sparse matrices).
(propagate_block): Make code a bit more efficient (for example,
no need to test `loop_depth' for each insn, just notes).
