cpu.x86.*: clean up signal handler prolog code
...
Also bump the signal handler frame sizes up again since it looks like we shrank them too much.

vm: strip out call-counting profiler
...
This makes the separate "code" and "entry_point" fields in word and quotation redundant, so also remove them to reclaim an additional cell per word and quotation object, which should help with #318 .

cpu.x86.bootstrap: don't safepoint in a safepoint
...
Safepointing in the signal-handler primitive causes a crash if the safepoint is guarded and the signal being handled was raised by a safepoint. Put our own RET in the subprimitive to bail out before the standard epilog gets written out. This tentatively appears to fix #349 .

Even if there's no stack frame we still need to safepoint before leaving the function. Fixes #332 .
