Patches buildMatchDeco and replaceAll all handle zero-length regex like .? and .*.

How to test:

Without patch:

$ npm run prepare && NODE_OPTIONS="--max-old-space-size=512" npm run test
FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
----- Native stack trace -----

With patch:

$ npm run prepare && NODE_OPTIONS="--max-old-space-size=512" npm run test
  48 passing (15ms)
