  Always redeclare clip/cull distance built-ins
  
  When clip or cull distance built-in arrays are implicitly
  sized, various pruning passes may produce an inconsistent
  AST state thus causing translation or linking failures.
  
  Adjusted the dedicated validation pass to inject
  an explicit declaration thus bypassing the issue.
  
  Additional updates:
  
  * Ensured that API clip distance state emulation is
    applied when a variable is declared but not assigned
  
  * Reverted previous clip/cull distance related changes to
    TIntermBinary::hasSideEffects as they are redundant now
  
  * Fixed failing AST validation for MSL varying emulation
  
  * Aligned linking error messages with the specifications
  
  * Updated tests and cleaned-up obsolete code
