  regcomp.c - add a PARNO() macro to wrap the ARG() macro

We used the ARG() macro to access the parno data for the OPNE
and CLOSE regops. This made it difficult to change the type and
size or location of this data in the node. Replacing this access
with a specific macro makes the code more legible and future proof.

This was actually backported from finding everything that broke
by changing the regnode type for OPEN and CLOSE to 2L and moving
the paren parameter to the 2L slot. We might do something like this
in the future and separating the PARNO() macros from their
implementation will make it easier.
