Not all compressed formats can be uploaded using glTexImage2D, that
only works if the extension provides an online texture-compressor. For
instance, EXT_texture_compression_s3tc only requires an online
compressor in the desktop version.
This test isn't really a test for the presence of an online-compressor,
this code is meant to test if we can render from it. But calling
glCompressedTexImage2D requires us to provide a valid compressed
payload, which is really awkward to maintain.
So let's instead just check for extensions to decide if these formats
are renderable or not.
Also, none of these compressed formats can be rendered to, so there's
no point in even testing for that.
Combined with a commit in mesa that enables EXT_texture_compression_s3tc
on GLES 2.0, this makes these dEQP-tests go from NotSupported to Pass

TGSI defines TGSI_SEMANTIC_SAMPLEPOS as a 4-component vector with
Z and W set to 0. However, if we ever try to reach thez and w
compoents, we run into trouble because this is implemented as a
swizzle on gl_SamplePosition instead. And gl_SamplePosition only
has x and y.
It seems that recent versions of mesa does just this, causing
shader-compilation errors during dEQP tests.
This fixes regressions in the following tests:
