aa264cee2d added align parameter to llvm.mc.Disassembler.decode 
i cant find any method in llvm to automatically get the
correct instruction alignment for disassembling. i thought
it would be MCAsmInfo.getMinInstAlignment, but that value is
1 for the ARM target machine. since that is clearly the wrong
instruction alignment for disassembling arm, the user should
be able to configure the alignment to whatever is needed.

3743146121 only convert input bytes if they are a string and we are in python 3 
in python 2 'str' and 'bytes' are the same. if input bytes are not
a string or bytes, then raise a TypeError.

8de5c3faff added some methods to llvm.mc.Operand 
methods that describe what type of operand it is

083586464b add bindings for instruction description methods to MCInstrDesc 
use these new bindings instead of MCInstrAnalysis bindings in
llvm.mc.Instr because MCInstrAnalaysis is just a thin layer
encapsulating MCInstrInfo that seems largely pointless.

0f3d5a8127 decode yields a tuple of integers instead of a bytearray 
a tuple of integers is immutable and more similar to python 3
bytes than bytearray

43f7330fda llvm.mc.Disassembler.decode now yields the byte sequence which generated the instruction 
added custom method to extra.h to return a PyBytes object
from the bytes read from MemoryObject.readBytes.

also moved the generic methods from StringRefMemoryObject
up to MemoryObject

fea82991c3 convert str input to bytes 
StringRefMemoryObject constructor binding specifies bytes as
its input parameter, so we have to convert it.

8dbfc377ad added functionality to llvm.mc.Instr to print itself 
uses binding of printInst on MCInstPrinter for printing
instruction.

also fixed a bug in llvm.mc.Disassembler.decode: idx should
start at zero, and we should pass code.getBase() + idx to
getInstruction. idx must start at zero because the while loop
compares it against code.getExtent() which returns only the
length of bs.

82d9c787f3 added llvm.mc.Operand class 
Operand encapsulates information that llvm provides about an MCOperand
in an instruction.

cbf4a61a17 moved the MC data type access to TargetMachine 
Disassembler now simply needs a TargetMachine object
and it will be able to access all the descriptor objects
it needs for disassembly through the target machine.

78be6a7f5f conditionals for compatibility with llvm < 3.4 
i only intend to support MC bindings (and anything reliant on MC)
for llvm 3.4 and greater.

38a00c6e55 fixed typo in new_from_triple and added args to new_from_name 
new_from_triple: need to pass subtarget info to new_from_target

new_from_name: allow caller to pass cpu and feature info

818c9289fc implemented binding for MCDisassembler.getInstruction 
also added new llvm.mc module to act as higher level
python access to the MC section of LLVM (added Instr
and Disassembler classes).

ba03b226c8 added Target.createMCSubtargetInfo and createMCDisassembler 
also added bindings to classes required by the target methods. also
added a convenience function to initialize all target components to
the llvm module
