explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

the remainder register.

Example:

bb0:
  x = 1
bb1:
  use(x)
  ...
  x = 2
  jump bb1

When x is isolated in bb1, the inner part breaks into two components, x1 and x2:

bb0:
  x0 = 1
bb1:
  x1 = x0
  use(x1)
  ...
  x2 = 2
  x0 = x2
  jump bb1

The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.

Mingw does not have the header <dbghelp.h>.
Thanks to Daniel Newton, testing it on mingw.
