/* Dean Gaudet's algorithm. To be most useful there must be a good way
to evaluate the C "conditional expression" (a?b:c construction) without
branching. The result of a?b:c is b if a is true (nonzero), and c if a
is false (0).
For example, a compare to zero op that sets a target GPR to 1 if the
operand is 0, and to 0 if the operand is nonzero, will do it. With this
instruction, the algorithm is entirely branch-free. But the most
interesting thing about it is the high degree of parallelism. All six
lines with conditional expressions can be executed in parallel (on a
machine with sufficient computational units).
Although the instruction count is 30 measured statically, it could
execute in only 10 cycles on a machine with sufficient parallelism.
The first two uses of y can instead be x, which would increase the
useful parallelism on most machines (the assignments to y, bz, and b4
could then all run in parallel). */

Table entries marked "u" are unused. 14 ops including a multiply,
plus an indexed load.
The smallest multiplier that works is 0x045BCED1 = 17*65*129*513 (all
of form 2**k + 1). There are no multipliers of three terms of the form
2**k +- 1 that work, with a table size of 64 or 128. There are some,
with a table size of 64, if you precede the multiplication with x = x -
(x >> 1), but that seems less elegant. There are also some if you use a
table size of 256, the smallest is 0x01033CBF = 65*255*1025 (this would
save two instructions in the form of this algorithm with the
multiplication expanded into shifts and adds, but the table size is
getting a bit large). */
