Title: Precision type of vec4

http://www.khronos.org/bugzilla/show_bug.cgi?id=781

Fixed illegal default precision qualifier in large-loop-test and added tests of all valid and invalid default precision qualifiers in vertex and fragment shaders. Filed ANGLE bug 410 about the failure of the new tests.
