math.intervals: Consistent handling of special intervals
...
Make both `empty-interval` and `full-interval` singletons, use generic functions
and methods where they are special-cased.
All words which work with interval points should also now work with the special
intervals.

compiler: on PPC, ANDI, ORI and XORI instructions take an unsigned 16-bit immediate, unlike ADDI, SUBI and MULLI which take a signed 16-bit immediate. The code generator was not aware of this, and so for example '[ >fixnum -16 bitand ]' would generate incorrect code. Split up small-enough? hook into immediate-arithmetic? and immediate-bitwise? and update value numbering to be aware of this. Fixes classes.struct bitfields test failure

Tuple layouts are now arrays, instead of built-in types. The superclass

array is now part of the tuple layout object itself, and class hashcodes
are stored alongside class words there. This removes 2 indirections when
reading a superclass, and 3 when reading a superclass hashcode.
