Nice speedup!

I ran a benchmark on PR 3862:

 1002  ./python ~/prog/python/performance/performance/benchmarks/bm_regex_compile.py --inherit=PYTHONPATH -v -o patch.json
 1003  git co master
 1004  make
 1005  ./python ~/prog/python/performance/performance/benchmarks/bm_regex_compile.py --inherit=PYTHONPATH -v -o ref.json
 1007  ./python -m perf compare_to ref.json patch.json 

Mean +- std dev: [ref] 396 ms +- 16 ms -> [patch] 347 ms +- 8 ms: 1.14x faster (-12%)

It's the following benchmark on *uncached* regular expressions. So it really measures re.compile() performance, not the cache.
