Test non-finite values with Float32List entrypoints

Chromium fails on the following call; Firefox and WebKit do not.

```js
// Uncaught TypeError: Failed to execute 'uniform1fv' on 'WebGLRenderingContext':
// The provided float value is non-finite.
gl.uniform1fv(location, [NaN]);
```

Relevant WebIDL entries:
```
typedef unrestricted float GLfloat;
typedef ([AllowShared] Float32Array or sequence) Float32List;
undefined uniform1fv(WebGLUniformLocation? location, Float32List v);
```
