[v3] <regex> implementation foundation, version 3

["Stephen M. Webb" <stephenw dot webb at bregmasoft dot ca>]

<regex> take 3.  The following have changed since version 2, at Paolo's 
request.

o  Some static const data members have been converted to enums where
   appropriate.
o  Definitions have been added for other static const data members.
o  Smaller member functions have been moved inline into the class
   definitions (a few placeholders have been left as out of line because
   their implementation is expected to be nontrivial and I am leery of
   pointless code churn).
o  Three more (xfailed) testcases.  More is better.
