- Renames select, swizzle, and shuffle to be consistent with the S128 and
existing S32x4 ops, and reflect that these aren't arithmetic.
e.g. I16x8Swizzle -> S16x8Swizzle.
- Implements S16x8 and S8x16 Select operations and tests.
- Implements S128And, Or, Xor, Not operations and tests.
- Implements Swizzle for 32x4 formats.
- Refactors test macros that generate SIMD code.

- Adds logical and arithmetic shifts for all integer types.
- Adds min and max for all integer types.
- Adds saturating add and subtract for small integer types.
- Removes lane operations from the MachineOperatorCache.

Reason for revert:
F32x4Add / Sub are still failing. I'll have to investigate on ARM hardware when I get back.

> and +Inf. Skip these tests until we have a way to do more sophisticated
> FP comparisons in the SIMD tests.
> - Eliminate a redundant F32x4 parameter for FP SIMD vector checking. We will only have this one FP type.

On ARM Neon at least, denormals flush to zero, which may not match
regular FP behavior.

This is more renaming work to comply with the naming in the public
design repository. E.g. types are called "value types" and we no longer
refer to ASTs.

The WasmRunner now always holds a TestingModule, and allows to add
several functions to it. The prepares a change to always run wasm code
with a full module behind it, removing the special handling for "no wasm
instance" at runtime (http://crrev.com/2551053002).
This CL here also templatizes the WasmRunner such that the Call method must
be called with the same signature specified for the WasmRunner. This
already catched several mismatches there.

- Add Simd128 type to Wasm AST types
- Add a pass that converts SIMD machine ops to runtime calls
- Sample opcodes Int32x4Splat, Int32x4ExtractLane and test
- Separate out generic SIMD Machine ops as these cannot be
handled by runtime functions just yet.
