Simplify and speed up numeric comparisons
This makes comparison functions (=, /=, <, <=, >, >=, min, max) quite
a bit faster (10-20 %). Bytecode ops on fixnums are not affected,
nor is `value<`.
* src/data.c (arithcompare): Simplify the code to reduce the number of
branches. Remove the comparison code argument; instead, return the
relation encoded as bits, which can be tested cheaply. All callers
adapted.
* src/lisp.h (enum Arith_Comparison): Remove.
(Cmp_Bit_*, cmp_bits_t): New.
