  Prefix user-defined names in GLSL output
  
  Now user-defined names are prefixed by _u in GLSL output in case name
  hashing is not on. Internal names such as names of temporary variables
  created in AST transformations are written out as such.
  
  This makes handling of internal function names and internal variable
  names consistent. It also removes the possibility of name conflicts
  between user-defined names and internal names in case name hashing is
  not on. In the same vein, it makes it safe to use GLSL reserved words
  that are not reserved in ESSL as variable names in case name hashing
  is not on.
  
  This also makes the GLSL output more consistent with how names are
  handled in HLSL output. Name hashing code is shared between
  VariableInfo and OutputGLSLBase to ensure names are handled
  consistently in both. The name that's used in the shader source for a
  given interface variable is written out to ShaderVariable::mappedName.
  
  An exception needs to be made for identifiers close to the length
  limit, since adding any prefix would take them over the limit. But
  they can be just written out as such, since we don't have any builtins
  or ANGLE internal variables that have as long names and could create a
  conflict.
