Software compiler for pre-compiling input regular expression.

Parameters:

pattern	Input regular expression.
bitset	Bit set map for each character class.
instructions	Compiled instruction list derived from input pattern.
instr_num	Number of instructions.
cclass_num	Number of character classes.
cpgp_nm	Number of capturing groups.
cpgp_name_val	Buffer of every name of each capturing group.
cpgp_name_oft	Starting offset addresses for the name of each capturing group.
