Allow use of complete interface of cerl_pmatch module
The cerl_pmatch module performs pattern matching compilation at the
level of Core Erlang. Functions that were not needed by the HiPE
compiler were ifdef-ed out. However, these functions may come handy
to other users; in particular a new testing tool currently under
development needs access to these functions.
While at it, added specs for these exported functions and also
strengthened the spec of another one.
