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

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

Improve code generation for shift word: add intrinsics for fixnum-shift-fast in the case where the shift count is not constant, transform 1 swap shift into a more overflow check with open-coded fast case, transform bitand into fixnum-bitand in more cases

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

define-inline now takes an effect parameter
...
C: now sets the stack effect of the new word to slot names
add new basis/constants vocab; CONSTANT: foo bar is equivalent to : foo bar ; inline
(going to fold CONSTANT:, ALIAS: and qualified into core soon perhaps)
tighten the screws: inline words now need a stack declaration too
update some usages of inline words

Various optimizations leading to a 10% speedup on compiling empty EBNF parser:
...
- open-code getenv primitive
- inline tuple predicates in finalization
- faster partial dispatch
- faster built-in type predicates
- faster tuple predicates
- faster lo-tag dispatch
- compile V{ } clone and H{ } clone more efficiently
- add fixnum fast-path to =; avoid indirect branch if two fixnums not eq
- faster >alist on hashtables
