Enable (type-directed) constant folding for LOGTEST on x86oids and PPC

 * COMBINATION-IMPLEMENTATION-STYLE can return :maybe. Like :default,
   it enables transforms, but transforms can call C-I-S themselves to
   selectively disable rewrites.

 * Implement type-directed constant folding for LOGTEST. !x86oids/PPC
   platforms get that for free via inlining.

 * Use :maybe to enable all LOGTEST transforms except inlining.
