glsl: Disallow float literals with the 'f' suffix but no point or exponent 

According to the GLSL spec float literals like ‘1f’ shouldn't be allowed
without adding a decimal point or an exponent. Apparently the AMD driver also
disallows this so it seems unlikely that anything would be relying on it.
