Add abbreviations to the TYPE_BLOCK for pointers, functions, structs and arrays.
This shrinks the type_block of kc++ from 139901 bits to 99389 bits (0.55% to 0.39%

add a char6 abbrev for bbnames and value names.  This represents each character
with 6 bits where possible.  This shrinks kc++ from 3324164B to 3183584B.  The
old VST was:

Implement support for globally associating abbrevs with block IDs, which
relieves us from having to emit the abbrevs into each instance of the block.
This shrinks kc.bit from 3368K to 3333K, but will be a more significant win
once instructions are abbreviated.
