  rts: Switch prim to use modern atomic compiler builtins
  
  The __sync_*() atomic compiler builtins have been deprecated in GCC
  for a while now and also don't provide variants for 64-bit values
  such as __sync_fetch_and_add_8().
  
  Thus, replace them with the modern __atomic_*() compiler builtins and
  while we're at it, also drop the helper macro CAS_NAND() which is now
  no longer needed since we stopped using the __sync_*() compiler builtins
  altogether.

  Decoupling L.H.S.Decls from GHC.Types.ForeignCall
  
    - Adding TTG extension point for 'CCallTarget'
    - Adding TTG extension point for 'CType'
    - Adding TTG extension point for 'Header'
    - Moving ForeignCall types that do not need extension
      to new L.H.S.Decls.Foreign module
    - Replacing 'Bool' parameters with descriptive data-types
      to increase clairty and prevent "Boolean Blindness"
