incorporating a significantly simpler "SlotMachine" into this file. The
SlotMachine is tailored for use by only the AsmWriter whose requirements
for slot numbers are vastly different than from the Bytecode/Writer. Code
change passes all Feature and Regression tests.

the Abstract Data Type that holds slot number values and associates them
with Type* and Value*. The SlotTable is simply the holder of the slot
numbers and provides a controlled interface for building the table. It does
not enforce any particular idiom or functionality for manipulating the slot
numbers.

This is part of bug_122. The SlotCalculator and SlotMachine classes will
follow.

SymbolTable will now assert if this is done. This didn't find any incorrect
usage of SymbolTable but will prevent future mistakes until Type != Value.

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.
