Repair hideif regexp problems

* lisp/progmodes/hideif.el (hif-white-regexp, hif-tokenize):
Avoid superlinear backtracking behaviour by rewriting regexps
to avoid nested repetitions and make positive progress each time.
Use lazy matching of the innards of /*...*/ comments to avoid
matching too much.
