Kristof Beyls 0ba797e8f7 Make ARMAsmPrinter generate the correct alignment specifier syntax in instructions.
The Printer will now print instructions with the correct alignment specifier syntax, like
    vld1.8  {d16}, [r0:64]

Benjamin Kramer 69d57cf9c4 Simplify some uses of utohexstr.
As a side effect hex is printed lowercase instead of uppercase now.

James Molloy 8067df9503 Second of a three-patch series aiming to fix MSR/MRS on Cortex-M. This adds predicate checking to the Disassembler.

Owen Anderson e0152a73c2 Replace the existing ARM disassembler with a new one based on the FixedLenDecoderEmitter.
This new disassembler can correctly decode all the testcases that the old one did, though
some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in
operand checking as the old one was.

Owen Anderson 454e1c7abb Remove VMOVDneon and VMOVQ, which are just aliases for VORR. This continues to simplify the path towards an auto-generated disassembler.

Johnny Chen 421316178e The ARM disassembler did not handle the alignment correctly for VLD*DUP* instructions
(single element or n-element structure to all lanes).

Johnny Chen c0e86fb965 The ARM disassembler was not recognizing USADA8 instruction. Need to add checking for register values
for USAD8 and USADA8.

Johnny Chen 2ac486e387 A8.6.92 MCR (Encoding A1): if coproc == '101x' then SEE "Advanced SIMD and VFP"
Since these "Advanced SIMD and VFP" instructions have more specfic encoding bits
specified, if coproc == 10 or 11, we should reject the insn as invalid.

Johnny Chen 8bca174f48 Fix a bug in the disassembly of VGETLNs8 where the lane index was wrong.
Also set the encoding bits (for A8.6.303, A8.6.328, A8.6.329) Inst{3-0} = 0b0000,
in class NVLaneOp.

Johnny Chen c3656d29f6 A7.3 register encoding
Qd -> bit[12] == 0
    Qn -> bit[16] == 0
    Qm -> bit[0]  == 0

If one of these bits is 1, the instruction is UNDEFINED.

Johnny Chen c5207f7167 The r118201 added support for VORR (immediate). Update ARMDisassemblerCore.cpp to disassemble the
VORRiv*i* instructions properly within the DisassembleN1RegModImmFrm() function.  Add a test case.
