pgbench: Support double constants and functions. The new functions are pi(), random(), random_exponential(), random_gaussian(), and sqrt(). I was worried that this would be slower than before, but, if anything, it actually turns out to be slightly faster, because we now express the built-in pgbench scripts using fewer lines; each \setrandom can be merged into a subsequent \set.
