2dcb5834c0 Rename a field so there's less confusion between fields of the same name.

832254e1c2 Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

Completely rewrite llvm-upgrade. This should be its final design. Any future
changes will use this same design.  The changes involve the following:

1. Make this work very much like the 1.9 AsmParser
2. Retain old upgrades dating back to release 1.2 time frame.
3. Merge in some of the upgrades between 1.9 and 2.0 (e.g. icmp/fcmp).
4. Attach a Signedness value (Signless, Unsigned, Signed) to every type,
   Value, Constant, Instruction, and list of those things in the Parser.
   Use these to make signedness decisions for instruction upgrades.
5. Implement unique name upgrade for function values and global values.
6. Identify rename cases that might cause problems and warn about them.
   For example: renaming a global variable with external linkage.
7. Generate a 2.0 IR using VMCore. This is necessary for numerous
   reasons and has the advantage that it never goes out of date.
8. Use the AsmPrinter to make the output nice.
9. Clean up error and warning messages from 1.9 form.

3d6cd1b149 For PR1113:
Increment the counter after the second use, not after the first use. This
fixes PR1113.

Also, rename some classes for simplicity and to more naturally be
reminscient of LLVM 1.9. This in preparation for additional classes that
will provide a scaled down model of the LLVM 1.9 IR.

e0a15bbc02 Reorganize things a bit in preparation for rewrite. Although this looks
like a lot, its really only two changes:

1. Move stuff that should be private to .y out of the .h file.
2. Make all semantic values pointers.

This cleans up the silly destroy methods and changes them to delete. It
also moves the TypeInfo and ValueInfo classes into the .y where we can
modify them more readily because they have no clients any more.

This shouldn't result in any functional changes in llvm-upgrade.

cb03b5a122 For PR1082:
Solve several related problems by making variable names more unique and
dealing with recursive phi nodes. Unfortunately, this doesn't solve the
main issue reported in the PR, but its a step in that direction.

90eb4d653c Major update of llvm-upgrade:
1. Completely revise the type system so that types are handled as const
   objects and not created multiple times, cloned, or otherwise copied.
   This gets around memory issues, saves memory, and also emulates LLVM's
   no-two-types-of-the-same-shape-created semantics.
2. Adjust the handling of global names. Basically, we cannot rename them
   for a variety of reasons: linking, forward references, etc.
3. Detect global names that have name conflicts as the result of collapsed
   type planes or redefinitions that llvm-as no longer accepts. These will
   produce warnings on stderr and one of the globals will be renamed.
4. Rename ParserInternals.h as UpgradeInternals.h so it doesn't conflict
   in the debugger with ParserInternals.h from lib/AsmParser.
5. Move the guts of the TypeInfo class into the grammar so we aren't
   implementing large functions in a header file. This also helps with
   debugging a bit.
