Unroll for-loop if sampler array uses loop index as its index. If inside a for-loop, sampler array index is the loop index, Mac cg compiler will crash. This CL unroll the loop in such situation. The behavior is: 1) If the for-loop index is a float, we reject the shader. 2) If it is an integer, we unroll the for-loop. Things that should be done in the future are: 1) Add line number macros. 2) Add a limit to unroll iteration count. anglebug=94 Review URL: http://codereview.appspot.com/4331048 git-svn-id: https://angleproject.googlecode.com/svn/trunk@606 736b8ea6-26fd-11df-bfd4-992fa37f6226
