373d2bccea For PR1064: 
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

d5ba7eadcc Provide a script that can track down which optimization pass causes 
different code to be produced between two llvm builds that differe slightly.
This is useful in tracking down mis-optimization bugs.

e52a08d399 This is a utility for preparing patches against LLVM. It runs cvs diff with 
the correct options, places the patch content in order that makes sense for
review, and filters cruft out of the patch (like diffs in *.cvs files). It
produces both a NAME.patch.raw (unfiltered) and NAME.patch (filtered) file.

4a2af4e374 Remove the isTwoAddress property from the CodeGenInstruction class. It should 
not be used for anything other than backwards compat constraint handling.

Add support for a new DisableEncoding property which contains a list of
registers that should not be encoded by the generated code emitter.  Convert
the codeemitter generator to use this, fixing some PPC JIT regressions.

796d72272b Fix a bug handling nodes with variable arguments. The code was fixed to assume 
that there were two input operands before the variable operand portion.  This
*happened* to be true for all call instructions, which took a chain and a
destination, but was not true for the PPC BCTRL instruction, whose destination
is implicit.

Making this code more general allows elimination of the custom selection logic
for BCTRL.

6921c1c0a7 Divide select methods into groups by SelectionDAG node opcodes (ISD::ADD, 
X86ISD::CMP, etc.) instead of SDNode names (add, x86cmp, etc). We now allow
multiple SDNodes to map to the same SelectionDAG node (e.g. store, indexed
store).
