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

Replace ratio and complex built-in types with tuples defined in the library. This frees up two lo-tags, so move array and quotation over to these tags and update compiler for new tags

Fix some problems with arithmetic type inference, exposed by recent changes to log2 word
...
- declared input type for bignum-shift was stricter than the runtime behavior, leading to bad propagation of type info if shift count was a bignum
- types inferred for type functions which used number-valued/integer-valued/real-valued were not always precise, eg bignum bignum bitxor => integer
- add interval-log2, type function for (log2)
- remove math-class-min, it was useless

Refactor all usages of >r/r> in core to use dip, 2dip, 3dip
...
Non-optimizing compiler now special-cases dip, 2dip, 3dip following a
literal quotation: this allows us to break the dip/slip meta-circle
without explicit calls to >r/r>
