This shrinks kc++ from 2815788 to 2724088 bytes, which means the bitcode
file is now smaller than the bytecode file.

implement the 'string constant' optimization.  This shrinks kc.bit from
2878544 to 2815788

further reduce the redundancy of types in the instruction encoding.  This
shrinks function bodies in kc++ from 891913B to 884073B

stop encoding type/value pairs when the type is implied by the value.
This shrinks the function block of kc++ from 1055K to 906K
