Disable two failing tests for now.
Fix the return type of SIMD.float64x2.splat
Remove "use strict" from the polyfill

Applications may wish to use the SIMD polyfill without having
"use strict" applied to themselves.

We can use "use strict" in the benchmark though, to ensure that all the
code works under it.

Minor fixes and simplifications
Implement new min/max semantics

Following the proposal in
https://github.com/johnmccutchan/ecmascript_simd/issues/67

These min and max functions follow the Math.min and Math.max semantics,
and are arguably the more intuitive and semantics.

This patch also introduces minNum and maxNum functions, which follow the
IEEE-754 minNum and maxNum semantics.
Add tests for minNum and maxNum.
Don't use floor for float-to-int conversion

The default rounding for float-to-int conversion should be truncation,
rather than floor.
Use consistent coercion in constructors

Make the SIMD constructors convert their scalar operands to their
desired types.
Simplify constructor coersion

Use |0 instead of a function which does conversion to int32 using a typed
array, and use Math.fround when available for converstion to float32.
Tests for floating-point comparisons.
Tests for integer comparisons.
Additional tests for abs, neg, and div
