Fix speed regressions in ES2 shaders

The GLSL ES specification (up to at least 3.0) does not mandate support of
dynamic indexing of uniform block arrays. For that reason loops in ES2
shaders were unrolled by calling separate functions, but it had leaded to
rendering speed regressions. This patch reverts loops unrolling using
separate functions and replaces dynamic indexing in place instead.
