Hash :b196eec0 Message :translator: Fix InitializeVariables with gl_ClipDistance.
The extension allows for the shader to redeclare this variable with
a different size. This would sometimes put the tree in an inconsistent
state when used with the InitializeVariables feature. Fix this by using
the user declaration of gl_ClipDistance when available.
Found when working on trace validation, where using the init output
variables option in the compiler would then cause tree validation to
fail for one specific test.
Test: ClipDistanceTest.ThreeClipDistancesRedeclared
