It appears that some bundling operations on Mac actually
require that all libraries have a unique name, since
output_dir is effectively ignored and overwritten in that
scenario, so I have to remove that renaming code on Mac so
that SwiftShader doesn't clash with Angle.

The following cl had broken all fragment uniform buffers:
https://swiftshader-review.googlesource.com/6950

Since the null pointer check was only made on the vertex
uniform buffer, it was preventing the fragment uniform
buffer from being set, which was causing a crash when this
happened.

There was a second issue  with this cl, which was allowing
'uniformBuffers[-1].get()' to be called, which should not
have been allowed.

Also, it is safer to call VertexProcessor::setUniformBuffer
and PixelProcessor::setUniformBuffer unconditionally in order
to set the null pointers correctly when no buffers are set.

Since the swiftshader libraries are loaded at runtime

There was a silly mistake in the code that I just found.
Instead of being ordered (1,2,3,4), the 4 pixels being
outputted were ordered (3,4,1,2), which was within the
tolerance threshold for most of the image, but exhibited
weird sparse diagonal lines of errors (values outside of
threshold). Reordered the pixels properly to fix the issue.

The default alpha value for integer types is 1 and not the
