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.

fee8ce6131 Fairly substantial changes to update the alias analysis we are querying as 
we make the transformation.  This allows us to use interprocedural alias
analyses successfully.

ac9ce5d851 Fix a bug in outputting branches to constant PCs. Since the PC is supplied as 
a full 64-bit address, it must be adjusted to fit in the branch instruction's
immediate field. (This is only used in the reoptimizer, for now.)

9adf9d8bfc Move RemapInstruction() to ValueMapper, so that it can be shared with 
CloneTrace, and because it is primarily an operation on ValueMaps.  It
is now a global (non-static) function which can be pulled in using
ValueMapper.h.

b41b628afd Clean up this pass somewhat: 
Add better comments, including a better head-of-file comment.
Prune #includes.
Fix a FIXME that Chris put here by using doInitialization().
Use DEBUG() to print out debug msgs.
Give names to basic blocks inserted by this pass.
Expand tabs.
Use InsertProfilingInitCall() from ProfilingUtils to insert the initialize call.
