This implements deferred compilation of regular expressions, which can appear often as module globals. The hope is that this can shave time off of application start up time. See the bpo issue for further discussion.

Update the test suite.
* Safely use LRU cache for compiled patterns.
* Make sure repr(), hash(),  ==, != "instantiate" the compiled rexex
* inline flag 'n' == the re.IMMEDIATE flag

I've updated the branch to include a compile_od() function, but I think for now I am going to abandon this experiment. I'm not convinced that adding another function will provide enough of a win for the ecosystem, even if it does turn out to improve start up time.
