Implement implicit conversions of function-call arguments (both in and out) as explicit conversions in the AST, through handleArgumentConversions().

Browse source 
Also
 - uniformly handle EvqConstReadOnly as an input argument in a function, with 
   isParamInput() and isParamOutput() queries in TQualifier.
 - provide a makeTemporary() in TQualifier, for erasing original qualification when making a temp
 - provide a makeInternalVariable() call to make a shader variable not seen in the shader source
