e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)
A update of langref will occur in a subsequent checkin.

create symbols. It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.
This fixes rdar://7807601.

These instructions use byte index in a control vector (M:Vm) to lookup byte
values in a table and generate a new vector (D:Vd). The table is specified via
a list of vectors, which can be:
{Dn}
{Dn D<n+1>}
{Dn D<n+1> D<n+2>}
{Dn D<n+1> D<n+2> D<n+3>}

input to be v8i8 or v16i8, which buildvectors get canonicalized to.
This allows the patterns that were previously using a bare 'vnot' to
match, before they couldn't.

it as the format for the appropriate N3V*SL*<> classes. These instructions
require special handling of the M:Vm field which encodes the restricted Dm and
the lane index within Dm.
Examples are A8.6.325 VMLA, VMLAL, VMLS, VMLSL (by scalar):
vmlal.s32 q3, d2, d10[0]

through to the generic version. The generic functions use STR/LDR, but T2
needs the t2STR/t2LDR instead so we get the addressing mode correct.

format argument as well.

to encode the byte location of the extracted result in the concatenation of the
operands, from the least significant end.
Modify VEXTd and VEXTq classes to use the format.

follow the N3RegFrm's operand order of D:Vd N:Vn M:Vm. The operand order of
N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand).
Add a parent class N3Vf which requires passing a Format argument and which the
N3V class is modified to inherit from. N3V class represents the "normal"
3-Register NEON Instructions with N3RegFrm.
Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift
Instructions and replace 8 invocations with it.

Absolute Difference and Accumulate Long), and VABD (Vector Absolute Difference).

dispatch to the appropriate routines to handle the different interpretations of
the shift amount encoded in the imm6 field. The Vd, Vm fields are interpreted
the same between the two, though.
See, for example, A8.6.367 VQSHL, VQSHLU (immediate) for N2RegVShLFrm format and
A8.6.368 VQSHRN, VQSHRUN for N2RegVShRFrm format.

These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP. The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.
