diexec.c: Cache a pointer directly to the machine scheduler at startup,
to eliminate device().machine().scheduler() chains all over the place (nw) This change has been sitting in my local tree for months, from when I was (mostly unsuccessfully) working on c64 performance. It gives a small speedup to drivers with many tightly-interleaved executing devices (i.e. Commodore drivers) I didn't think it was worth making everyone do a clean build for such tiny gains but I didn't have the heart to chuck it. Since I'm already making another core-touching, clean-build-needed commit tonight, in it goes.
