Revert "glsl: Replace constant-index vector array accesses with swizzles"

This reverts commit dbf94d105a48b7aafb2c8cf64d8b4392d87efea1, which
was working around a bug in the handling of array indexing when
constant folding built-in functions.  Now that the constant folding
bug has been fixed, the workaround is no longer needed.
