Instead of allocating and embedding certain heap numbers into the code
during code assembly, emit dummies but record the allocation requests.
Later then, in Assembler::GetCode, allocate the heap numbers and patch
the code by replacing the dummies with the actual objects. The
RelocInfos for the embedded objects are already recorded correctly when
emitting the dummies.

- Adds unary Reverse shuffles (swizzles): S32x2Reverse, S16x4Reverse,
S16x2Reverse, S8x8Reverse, S8x4Reverse, S8x2Reverse. Reversals are
done within the sub-vectors that prefix the opcode name, e.g. S8x2
reverses the 8 consecutive pairs in an S8x16 vector.
- Adds binary Zip (interleave) left and right half-shuffles to return a
single vector: S32x4ZipLeft, S32x4ZipRightS16x8ZipLeft, S16x8ZipRight,
S8x16ZipLeft, S8x16ZipRight.
- Adds binary Unzip (de-interleave) left and right half shuffles to return
a single vector: S32x4UnzipLeft, S32x4UnzipRight, S16x8UnzipLeft,
S16x8UnzipRight, S8x16UnzipLeft, S8x16UnzipRight.
- Adds binary Transpose left and right half shuffles to return
a single vector: S32x4TransposeLeft, S32x4TransposeRight,
S16x8TransposeLeft, S16xTransposeRight, S8x16TransposeLeft,
S8x16TransposeRight.
- Adds binary Concat (concatenate) byte shuffle: S8x16Concat #bytes to
paste two vectors together.

We also initialize the Isolate on creation.
This should allow for getting rid of the last remaining default isolate
traces. Also, it'll speed up several isolate related operations that no
longer require locks.
Embedders that relied on v8::Isolate to return an uninitialized Isolate
(so they can set ResourceConstraints for example, or set flags that
modify the way the isolate is created) should either do the setup before
creating the isolate, or use the recently added CreateParams to pass e.g.
ResourceConstraints.
