460e94d842 Add support for the PPC isel instruction. 
The isel (integer select) instruction is supported on the 440 and A2
embedded cores and on the POWER7.

1c0541b031 Move getOpcodeName from the various target InstPrinters into the superclass MCInstPrinter. 
All implementations used the same code.

dab9e35ad0 Remove getInstructionName from MCInstPrinter implementations in favor of using the instruction name table from MCInstrInfo. Reduces static data in the InstPrinter implementations.

bcc3fadad9 These do not need to be conditional on the presence of CommentStream, as they have a fallback path now.

69fa8ffeef In the disassembler C API, be careful not to confuse the comment streamer that the disassembler outputs annotations on with the streamer that the InstPrinter will print them on.

a0c3b97221 Don't attach annotations to MCInst's. Instead, have the disassembler return, and the printer accept, an annotation string which can be passed through if the client cares about annotations.

instructions, allowing is to eliminate some dead operand 
printing methods from the instprinter.

edb9d84dcc add targetoperand flags for jump tables, constant pool and block address 
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.

7a5c57ecf4 Implement support for printing register and immediate operands, 
add support for darwin vs aix syntax.  We now can print instructions
like this:

	add r3, r3, r4
	blr 

and (in aix mode):
	add 3, 3, 4
	blr
