reinterpret_casts (possibly indirectly via C-style/functional casts)
on values, e.g., 

  int i;
  reinterpret_cast<short&>(i);

The IR generated for this is essentially the same as for

  *reinterpret_cast<short*>(&i).

Fixes PR6437, PR7593, and PR7344.

mostly in avoiding unnecessary work at compile time but also in producing more
sensible block orderings.

Move the destructor cleanups for local variables over to use lazy cleanups.
Eventually all cleanups will do this;  for now we have some awkward code
duplication.

Tell IR generation just to never produce landing pads in -fno-exceptions.
This is a much more comprehensive solution to a problem which previously was
half-solved by checks in most cleanup-generation spots.

It would be reasonable to just return false - an empty interval doesn't overlap
anything, but I want to know who is doing it first.

Extend the r107852 optimization which turns some fp compare to code sequence using only i32 operations. It now optimize some f64 compares when fp compare is exceptionally slow (e.g. cortex-a8). It also catches comparison against 0.0.
