5025a48f68 AArch64: add missing ACLE intrinsics mapping to general arithmetic operation from VFP instructions. 
E.g. float64x1_t vadd_f64(float64x1_t a, float64x1_t b) -> FADD Dd, Dn, Dm.

15945a0b70 Remove dead code. 
MO_JumpTableIndex and MO_ExternalSymbol don't show up on inline asm.

Keeping parts of the old asm printer just to print inline asm to a string that
we then parse back looks like a hack.

7fd70e7b0c AArch64: The pattern match should check the range of the immediate value. 
Or we can generate some illegal instructions.
E.g. shrn2 v0.4s, v1.2d, #35. The legal range should be in [1, 16].

    echo "0x00 0x00 0x80 0x0d" | ../bin/llvm-mc -triple=aarch64 -mattr=+neon -disassemble
will be disassembled into the same instruction st1 {v0b}[0], [x0], x0.

b21ab43cfc Revert r194865 and r194874. 
This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
  Base *foo = new Child();
  delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

65d1be119b AArch64: refactor vector list creation to be more uniform 
Instructions taking a vector list (e.g. "ld2 {v0.2d, v1.d2}, [x0]") need a
special register-class to deal with the constraints, and C++ code to support
selection. However, that C++ code can be made reasonably uniform to simplify
the selection process. Hence this patch.

No functionality change, so no tests.

627ef0cf5e AArch64: use default asm operand printing when modifier inapplicable 
If an inline assembly operand has multiple constraints (e.g. "Ir" for immediate
or register) and an operand modifier (E.g. "w" for "print register as wN") then
we need to decide behaviour when the modifier doesn't apply to the constraint.

Previousely produced some combination of an assertion failure and a fatal
error. GCC's behaviour appears to be to ignore the modifier and print the
operand in the default way. This patch should implement that.

d29bae8bc9 AArch64: enable MISched by default. 
Substantial SelectionDAG scheduling is going away soon, and is
interfering with Hao's attempts to implement LDn/STn instructions, so
I say we make the leap first.

There were a few reorderings (inevitably) which broke some tests. I
tried to replace them with CHECK-DAG variants mostly, but some too
complex for that to be useful and I just reordered them.

This patch fixes an old FIXME by creating a MCTargetStreamer interface

The ARM streamer is still declared in a common place because it is

completely hidden in the corresponding Target directories.

3e84ad28d4 ISelDAG: spot chain cycles involving MachineNodes 
Previously, the DAGISel function WalkChainUsers was spotting that it
had entered already-selected territory by whether a node was a
MachineNode (amongst other things). Since it's fairly common practice
to insert MachineNodes during ISelLowering, this was not the correct
check.

Looking around, it seems that other nodes get their NodeId set to -1
upon selection, so this makes sure the same thing happens to all
MachineNodes and uses that characteristic to determine whether we
should stop looking for a loop during selection.

This should fix PR15840.

630c5e06d6 AArch64: use RegisterOperand for NEON registers. 
Previously we modelled VPR128 and VPR64 as essentially identical
register-classes containing V0-V31 (which had Q0-Q31 as "sub_alias"
sub-registers). This model is starting to cause significant problems
for code generation, particularly writing EXTRACT/INSERT_SUBREG
patterns for converting between the two.

The change here switches to classifying VPR64 & VPR128 as
RegisterOperands, which are essentially aliases for RegisterClasses
with different parsing and printing behaviour. This fits almost
exactly with their real status (VPR128 == FPR128 printed strangely,
VPR64 == FPR64 printed strangely).

715d98d657 Add an instruction deprecation feature to TableGen. 
The 'Deprecated' class allows you to specify a SubtargetFeature that the
instruction is deprecated on.

The 'ComplexDeprecationPredicate' class allows you to define a custom
predicate that is called to check for deprecation.
For example:
  ComplexDeprecationPredicate<"MCR">

would mean you would have to define the following function:
  bool getMCRDeprecationInfo(MCInst &MI, MCSubtargetInfo &STI,
                             std::string &Info)

Which returns 'false' for not deprecated, and 'true' for deprecated
and store the warning message in 'Info'.

The MCTargetAsmParser constructor was chaned to take an extra argument of
the MCInstrInfo class, so out-of-tree targets will need to be changed.
