Add alien-assembly form for inline assembler, works like alien-invoke except calls a user-supplied quotation instead of generating a subroutine call. Replaces FPU status control, SSE detection and read timestamp routines in vm/cpu-x86.*S

vm: big overhaul of non-optimizing compiler
...
- change some primitives into sub-primitives: fixnum+ fixnum- fixnum* inline-cache-miss inline-cache-miss-tail
- rename some relocation types for clarity
- some other minor re-organizations and cleanups

compiler.cfg: remove _gc instruction, it doesn't need to exist, and change GC checks to ensure that the right amount of space is available instead of blindly checking for 1Kb

compiler.cfg.linear-scan now supports partial sync-points where all registers are spilled; taking advantage of this, there are new trigonometric intrinsics which yield a 2x performance boost on benchmark.struct-arrays and a 25% boost on benchmark.partial-sums

_gc instruction doesn't need slot to hold GC root area size, since that's just tagged-values>> length

compiler.cfg: if a block has an instruction that kills values it must be the only instruction in the block

Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint
