Owen Anderson c3c7f5dd56 Add support to the ARM MC infrastructure to support mcr and friends. This requires supporting
the symbolic immediate names used for these instructions, fixing their pretty-printers, and
adding proper encoding information for them.

With this, we can properly pretty-print and encode assembly like:
	mrc p15, #0, r3, c13, c0, #3

Fixes <rdar://problem/8857858>.

Bill Wendling 092a7bdf9f The tLDR et al instructions were emitting either a reg/reg or reg/imm
instruction based on the t_addrmode_s# mode and what it returned. There is some
obvious badness to this. In particular, it's hard to do MC-encoding when the
instruction may change out from underneath you after the t_addrmode_s# variable
is finally resolved.

The solution is to revert a long-ago change that merged the reg/reg and reg/imm
versions. There is the addition of several new addressing modes. They no longer
have extraneous operands associated with them. I.e., if it's reg/reg we don't
have to have a dummy zero immediate tacked on to the SDNode.

There are some obvious cleanups here, which will happen shortly.

Jim Grosbach 7ec3d34553 Pseudo-ize Thumb2 jump tables with explicit MC lowering to the raw
instructions. This simplifies instruction printing and disassembly.

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 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.
