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

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

Tweak string representation; high bit indicates if character has high bits in aux vector. Avoids memory access in common case. Split set-string-nth into two primitives; set-string-nth-fast is open-coded by optimizing compiler. 13% improvement on reverse-complement

Faster generic arithmetic on fiixnums: both-fixnums? sub-primitive performs a check if the top two stack items are both fixnums with a single conditional branch
