cast refactoring

  - add CAST(T, v) to cast vector v to type T
  - rewrite LOAD_3 and LOAD_4 to look a bit more like this new CAST

I'm getting tired of reading X_from_Y() casts.

This should let express all those casts uniformly, using Clang's
__builtin_convertvector() if possible.  GCC doesn't have that builtin,
so it still needs the long forms.
