[Bug regex/1302] New: improve regex bitset performance (don't assume 32 bits)


The regex bitset code currently uses an array of unsigned int words to
represent a bitset, and assumes these words are exactly 32 bits wide.
On modern 64-bit hosts, using a 64-bit word would require
approximately half the instructions for the bitset-related code.
Also, it's better not to assume 32-bits everywhere.  I'll attach a
patch.
