Make type caches perform better.
This change "interns" a chosen few parsed type specifiers,
importantly (CONS T T), NULL, and BOOLEAN, so that exactly one
of each exists, thereby reducing TYPE= to EQ in the affirmative
case. In addition to producing less garbage, the compiler
runs 3% to 4% faster on several files from its own sources.
