intrinsics revamp (trunk only)

Simplify many of the intrinsics macros from
  #define xxx_resistance (Hxxx || Exxx || resists_xxx(&youmonst))
down to
  #define xxx_resistance (Hxxx || Exxx)
by setting or clearing an extra bit in Hxxx during polymorph so that the
resists_xxx() check becomes implicit.

     Unfornately there were lots of places in the code that treat Hxxx
as a timeout number--primarily for Stunned, Confused, and Hallucination;
Stunned happens to be one of the revised macros--rather than as a bit
mask, so this patch needed a lot more changes than originally antipated.
