b731e87649 For VLDM/VSTM (Advanced SIMD), set encoding bits Inst{11-8} to 0b1011.

208d76cad9 For VMOV (immediate), make some of the encoding bits (cmode and op) unspecified.
For VMOVv*i[16,32], op bit is don't care, and some cmode bits vary depending on
the immediate values.

Ref: Table A7-15 Modified immediate values for Advanced SIMD instructions.

f81bf15552 Massive refactoring of NEON instructions. Separate opcode from data size specifier suffix, move \t up stream to instruction format, and fix more 80 column violations.
This fixes the NEON asm printing so the "predicate" field is printed between the opcode and the data type suffix.

da1aea4d75 Partially revert r84730 by removing N2VDup from ARMInstrFormats.td and modifying
VDUPLND and VDUPLNQ to derive from N2V instead of N2VDup.  VDUPLND and VDUPLNQ
now expect op19_18 and op17_16 as the first two args.

5c376ff9f0 Added NLdStLN which is similar to NLdSt with the exception that op7_4 is not
fully specified at this level.  Subclasses of NLdStLN can specify selective
bit(s) for Inst{7-4}, as is done for VLD[234]LN* and VST[234]LN* inside
ARMInstrNEON.td.

54c78ef2fe Print VMOV (immediate) operands as hexadecimal values. Apple's assembler
will not accept negative values for these.  LLVM's default operand printing
sign extends values, so that valid unsigned values appear as negative
immediates.  Print all VMOV immediate operands as hex values to resolve this.

3a639a07ea Do not infer the target type for COPY_TO_REGCLASS from dest regclass, this won't work if it can contain several types. Require explicit result type for the node for now. This fixes PR5364.
PS: It seems that blackfin usage of copy_to_regclass is completely bogus!
