9f6c4c141f Use NEON vmin/vmax instructions for floating-point selects. 
Radar 7461718.

69bfbd61c6 Remove the NEON N2VSInt instruction class: it's only used in one place and 
since it has no pattern, there's not much point in distinguishing an "N2VS"
class for intrinsics anyway.

3c0f96e054 More cleanup for NEON: 
* Use "S" abbreviation for scalar single FP registers in class and pattern
names, instead of keeping the "D" (for "double") abbreviation and tacking on
an "s" elsewhere in the name.
* Move the scalar single FP register classes and patterns to be more
consistent with other definitions in the file.
* Rename "VNEGf32d" definition to "VNEGfd" for consistency.
* Deleted the N2VDIntsPat pattern; N2VSPat is good enough.

9fedc33ca8 Emit spaces after commas in Neon register lists. This is more consistent 
with the rest of the assembly output, is easier to read, and matches the
expected output for gcc's Neon tests.

3a4a832223 The Neon "vtst" instruction takes a suffix that is the element size alone -- 
adding an "i" to the suffix, indicating that the elements are integers, is
accepted but not part of the standard syntax.  This helps us pass a few more
of the Neon tests from gcc.

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.

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!
