Make M\ throw an error upon lookup failure. Change method -> ?lookup-method, lookup-method is the throwing version of ?lookup-method. Fixes #229 .

math: add unordered comparison operators u< u<= u> u>= which behave exactly like < <= > >= except no floating point exceptions are set if one or both inputs are NaNs; also add efficient intrinsic for unordered? predicate, and fix propagation type functions for abs, absq, and bitnot

More optimization intended to reduce compile time. Another 10% speedup on compiling empty PEG parser
...
- new map-flat combinator replaces usages of 'map flatten' in compiler
- compiler.tree.def-use.simplified uses an explicit accumulator instead of flatten
- compiler.tree.tuple-unboxing uses an explicit accumulator instead of flatten
- fix inlining regression from last time: custom inlining results would sometimes be discarded
- compiler.tree's 3each and 3map combinators rewritten to not use flip
- rewrite math.partial-dispatch without locals (purely stylistic, no performance increase)
- hand-optimize flip for common arrays-of-arrays case
- don't run escape analysis and tuple unboxing if there are no allocations in the IR

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
