* Usage: timer ncomp nexec nsub
* or
* timer ncomp nexec nsub regexp string [ answer [ sub ] ]
*
* The second form is for timing repetitions of a single test case.
* The first form's test data is a compiled-in copy of the "tests" file.
* Ncomp, nexec, nsub are how many times to do each regcomp, regexec,
* and regsub. The way to time an operation individually is to do something
* like "timer 1 50 1".
