LUMINANCE and ALPHA textures should not be renderable

Check that attaching these texture types results in an incomplete
framebuffer instead of trying to render to that framebuffer. This helps
to ensure that unspecified rendering to these texture types is not
supported in any implementation, maintaining compatibility.

For reference, see OpenGL ES 2.0 spec section 4.4.5 Framebuffer
Completeness, specifically table 4.5. "Renderbuffer image formats", which
enumerates all renderable formats. Rendering to other formats is not
specified.
Revert change to the frozen 1.0.2. suite

Changing future versions of the conformance suite is enough, the 1.0.2
test should also pass in case the new more stringent version passes.

LUMINANCE and ALPHA textures should not be renderable
Based on feedback from Guillaume Abadie on public_webgl, removed invalid call of "isVertexArrayOES()" from oes-vertex-array-object test, as far back as version 1.0.1 of the conformance suite.

Account for literal constants taking up uniform storage

According to GLSL ES spec 10.0.17 Appendix A section 7:

"When calculating the number of uniform variables used, any literal
constants present in the shader source after preprocessing are included
when calculating the storage requirements. Multiple instances of
identical constants should count multiple times."
Better explanation of literal constants taking up space
Based on feedback from Brian Cornell on public_webgl, clarified that length of ArrayBufferView is actually byteLength in all compressed texture extensions.

Don't use premultiplied alpha in most GLSL generator tests

Many GLSL function conformance tests can generate superluminal color
values, where red, green or blue > alpha. Since browsers don't do
clamping for these color values before they are unpremultiplied and
encoded as PNG when toDataURL is called, the on-screen display of these
tests did not reflect the actual numeric values generated by the shader.
This complicated debugging failed tests. Fix this by switching to a
context with a non-premultiplied drawing buffer in these tests.

This issue does not affect the programmatic comparison of test results,
since that is being done using readPixels.
Revert change to the frozen 1.0.1 suite

It makes sense to fix displaying superluminal values in 1.0.2, since lots
of implementations are still working on conformance, but with 1.0.1 it's
better to avoid this kind of changes.
