Add new instruction vpaddl for signed and unsigned integers, adding
assembler, disassembler, simulator support, and also tests.
The signed and unsigned opcodes for vpaddl are separate enums, because
the helper EncodeNeonUnaryOp only takes a NeonSize (not NeonDataType). I
considered changing the signature, but none of the other instructions
use a NeonDataType, so it seems unnecessary.

These instructions should always treat inputs as signed, and saturate to
unsigned min/max values.
E.g. given -1, it should saturate to 0.
The spec text,
https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md#integer-to-integer-narrowing,
has been updated to describe this.
The changes here include codegen changes to ia32, x64, arm, and arm64,
changes to arm simulator, assembler, and disassembler to handle the case
of treating input as signed and narrowing to unsigned. The vqmovn
instruction can handle this case, our assembler wasn't allowing callers
to specify this.
The interpreter and scalar lowering are also fixed with this change.

return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.
Patchset 1 was auto-generated by using this clang AST matcher:
callExpr(
callee(
cxxMethodDecl(
hasName("start"),
ofClass(hasName("v8::internal::Vector")))
),
argumentCountIs(0))
Patchset 2 was created by running clang-format. Patchset 3 then

when necessary. This changes the Word32ReverseBytes operator to be

This further improves the performance on the dataviewperf.js test
