fd8ec07a8e Fix bug with previous implementation: 
-      // ~(c-X) == X-(c-1) == X+(-c+1)
+      // ~(c-X) == X-c-1 == X+(-c-1)

Implement: C - ~X == X + (1+C)

c6a7c83333 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

8dadbe31dc Update verifySavedState()'s comment, so that it reflects its current 
status.  In doFinalization(), skip over external functions, just like
Anand's mapping info does.

3e30e40801 Checking in Chris's suggestions: 
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

414e572f11 Significantly simplify constant emission by unifying the stuff which used to build up 
strings with the stuff that used to print to an ostream directly.  We now NEVER build
up big strings, only to print them once they are formed.

a71b07eeca All DSGraphs keep a reference to the targetdata they are created with. This is 
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

4db6e0ea7a The "correct" fix for CBackend/2003-10-23-UnusedType.ll is to not even try 
to emit types which are not used.

29f03b2d39 Including the symbol table in the FindUsedTypes analysis was the WRONG way 
to fix test/Regression/CBackend/2003-10-23-UnusedType.ll.  This completely
neutered the deadtypeelim pass.
