a1a78f0b68 Fix PR344: the incorrect remove was being used.

70d84370e1 A quick and ugly hack to fix PR345. I used TypeTy specifically to make 
Reid cringe :)

dccf1747a1 Part of bug 122: 
This change removes the BuildBytecodeInfo flag from the SlotCalculator
class. This flag was needed to distinguish between the Bytecode/Writer
and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can
remove this flag and simplify some code. Also, some minor name changes
to CachedWriter.h needed to be committed (missed in previous commit).

58bad426cc Part of bug 122. Removed dependency of AsmWriter on SlotCalculator by 
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.

8e6d7148c1 Make the constructor explicit so we can't implicitly convert bool to 
SlotTable.

92adcaf58c Adding the initial implementation of the SlotTable class. This class is 
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.

2791d48685 Made it illegal to pass a Type* through one of the Value* interfaces. The 
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.

e6e0da0b9f Completely rewrote the class. SymbolTable now separates Type* from Value* in preparation\ 
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.

66f55c8e78 Implement InstCombine:shift.ll:test16, which turns (X >> C1) & C2 != C3 
into (X & (C2 << C1)) != (C3 << C1), where the shift may be either left or
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.
