[Bug target/23983] New: the altivec builtins should be marked as pure/const

[pinskia at gcc dot gnu dot org]

#   TMT.5_729 = V_MAY_DEF <TMT.5_727>;
  #   TMT.6_730 = V_MAY_DEF <TMT.6_728>;
  y0_351 = __builtin_altivec_vrsqrtefp (B_350);

Almost all of the altivec builtins could be marked as pure/const and should 
cause less VOPS to be 
added for altivec code.
