GLES3: complex exprs, side effects, short circuits

GLES3: complex exprs, side effects, short circuits

Some of these 8 tests (the 4 that rely on short circuiting) fail on
Nexus6P/7.0 (they were fixed in 8.0 and pass on Pixel2016/8.1):
  https://crbug.com/695685
This is a port from WebGL:
  https://github.com/KhronosGroup/WebGL/blob/master/sdk/tests/conformance2/glsl3/array-in-complex-expression.html
  https://github.com/KhronosGroup/WebGL/blob/master/sdk/tests/conformance2/glsl3/short-circuiting-in-loop-condition.html
All of those tests are ported just for completeness.
