regen/regcomp.pl - create typedefs for all regnode types

Currently we hard code the struct used by the different regop types.
This makes it awkward to change the structure used by a specific regop
as the struct it uses might be used in many contexts, and each cases
of a regop using that structure must be reviewed to see if it needs
to be changed.

This patch adds a typedef for each regnode. The typedefs are named
'tregnode_OP', for instance 'tregnode_TRIE' is typedefed to 'struct
charclass' (at the time of this commit). This allows the code to do
things like 'sizeof(tregnode_TRIE)' and should the exact struct used
for TRIE regops change in the future then no code need be reviewed
or changed.
