compiler.cfg.representations: fix various bugs

compiler.cfg.representations: add more peephole optimizations to reduce fixnum tagging and untagging overhead

compiler.cfg: merge all alien accessors into ##load-memory-imm and ##store-memory-imm

compiler.cfg.representations: peephole optimizations are used to simplify the case where the input to a ##shl-imm or ##sar-imm needs to be untagged

Untagged fixnums work in progress

compiler: combine ##load-constant followed by ##alien-double into a ##load-double on x86-32, saving an integer register

More SIMD work
...
- Rename SIMD types and register representations: <type>-<count> rather than <count><type>-array
- Make a functor to define 256-bit vector types, use it to define float-8 type
- Make SIMD instructions pure-insns so that they participate in value numbering

compiler.cfg: virtual registers are integers now, and representations are stored off to the side. Fix bug in representation selection that would manifest if a value was used as a float and a fixnum in different branches; cannot globally unbox float in this case

e21ca289c3
compiler.cfg.representations: new pass to make global unboxing decisions, relies on new compiler.cfg.loop-detection pass for loop nesting information
