92b5a2eb16 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.

e6913600c7 Break ARM addrmode4 (load/store multiple base address) into its constituent 
parts. Represent the operation mode as an optional operand instead.

6274ec48b3 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.

ab682a2090 PLD, PLDW, PLI encodings, plus refactor their use of addrmode2.

77aee8e22c LDRi12 machine instructions handle negative offset operands normally (simple 
integer values), not with the addrmode2 encoding.

3e55612472 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.

b3af5de2d9 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.

"lane" operand modifier.

7ac1609a3b 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.
