provide range info for several new X86Operands.

Remove most of old Mach-O Writer support, it has been replaced by MCMachOStreamer

Further refactoring to completely remove MachOWriter and drive the object file
writer with the AsmPrinter MCInst/MCSection logic is forthcoming.

the default implementation returns "unknown".

the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

Pass in SMLoc of instr opcode into ParseInstruction.
Make AsmToken be a class, not a struct.

- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

with -disassemble, llvm-mc now accepts lines of the
form
0x00 0x00
and passes the resulting bytes to the disassembler for
the chosen (or default) target, printing the result.

Checks that the code generated by 'tblgen --emit-llvmc' can be actually
compiled. Also fixes two bugs found in this way:

- forward_transformed_value didn't work with non-list arguments
- cl::ZeroOrOne is now called cl::Optional
