Shader validator must reject default precision qualifier with illegal type operand

[GoogleCodeExporter]

In http://www.khronos.org/bugzilla/show_bug.cgi?id=781 it was pointed out that 
the statement "precision highp vec4;" was accidentally included in a new 
conformance test. It was an accident that highp was used, but in addition, vec4 
is an illegal type in a default precision statement. The only valid types are 
int, float and the sampler types. The shader translator needs to be fixed to 
fail compilation in this case.

New conformance tests verifying this:

Actually already fixed. I forgot to link to this bug in the code review.
