for making Type not derive from Value. There are now separate interfaces \
for looking up, finding, and inserting Types and Values. There are also \
three separate iterator interfaces, one for type planes, one for the types \
(type type plane), and one for values within a type plane. See the \
documentation in the Header file.

right and the compare may be any one.

This triggers 1546 times in 176.gcc alone, as it is a common pattern that
occurs for bitfield accesses.
