glsl: Try vectorizing when seeing a repeated assignment to a channel.

When considering assignment expressions like:

    v.x += u.x;
    v.x += u.x;

the vectorizer would incorrectly keep going, attempting to find more
instructions to vectorize.  It would overwrite the saved assignment
to point at the second one, and increment channels a second time,
resulting in try_vectorize thinking the expression was a vec2 instead of
a float.

Instead, if we see a repeated assignment to a channel, just try to
vectorize everything we've found so far.  This clears the saved state
so it will start over.

Fixes Piglit's repeated-channel-assignments.vert.

linker: Set block bindings based on UniformBlocks rather than UniformStorage

For blocks, gl_shader_program::UniformStorage isn't very useful.  The
names stored there are the names of the elements of the block, so
finding blocks with an instance name is hard.  There is also only one
entry in ::UniformStorage for each element of a block array, and that is
a deal breaker.

Using ::UniformBlocks is what _mesa_GetUniformBlockIndex does.  I
contemplated sharing code between set_block_binding and
_mesa_GetUniformBlockIndex, but building the stand-alone compiler and
the unit tests make this hard.  I plan to return to this effort shortly.

That means we can't use ::UniformStorage to select between the sampler

mesa: Prefer non-swizzled formats for most sized internalformats

These formats can be cast to others (with different component types or
sizes) via ARB_texture_view or ARB_shader_image_load_store. We want
them to be laid out consistently so that we can just reinterpret the
memory with a different format.

In V1, this was done conditionally on a 'prefer_no_swizzle' flag which
was set in TexStorage/TextureView paths, but we need the same behavior
for ARB_shader_image_load_store (which also works with images created
via TexImage, so we don't want it to be conditional.

that the dri module will always have a .so extension, thus it will fail
