Bill Wendling a68e3a5397 Encode the multi-load/store instructions with their respective modes ('ia', 
'db', 'ib', 'da') instead of having that mode as a separate field in the
instruction. It's more convenient for the asm parser and much more readable for
humans.

Bill Wendling f2fa04acfc Minor cleanups: 
- Get the opcode once.
- Add a ParserMatchClass to reglist.

Evan Cheng 9c40af415f For pre-v6t2 targets, only select MOVi32imm if the immediate can be handled with movi + orr.

Bill Wendling e84eb99cbb The MC code couldn't handle ARM LDR instructions with negative offsets: 
vldr.64 d1, [r0, #-32]

The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

printOperand() asm printer helper functions. rdar://8425198

Jim Grosbach c6af2b4066 Break ARM addrmode4 (load/store multiple base address) into its constituent 
parts. Represent the operation mode as an optional operand instead.

Chris Lattner f20f79808e hook up getOpcodeName for ARM so that "llc -show-mc-inst" includes 
the opcode string in the inst dump, e.g.:
	vmov	r2, r3, d17             @ encoding: [0x31,0x2b,0x53,0xec]
                                        @ <MCInst #989 VMOVRRD
                                        @  <MCOperand Reg:68>
                                        @  <MCOperand Reg:69>
                                        @  <MCOperand Reg:19>
                                        @  <MCOperand Imm:14>
                                        @  <MCOperand Reg:0>>

The "VMOVRRD" is new.

Jim Grosbach 9d2d1f0f00 LDRi12 machine instructions handle negative offset operands normally (simple 
integer values), not with the addrmode2 encoding.

Jim Grosbach 1e4d9a17c2 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

Jim Grosbach 7e72ec6626 Refactor the ARM 'setend' instruction pattern. Use a single instruction pattern 
and handle the operand explicitly. Flesh out encoding information. Add an
explicit disassembler testcase for the instruction.

Jim Grosbach 0e854f3d43 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.
