original report didn't come with a testcase, and I can't come up with a case
that actually fails.

a Twine, e.g., for names).
 - I am a little ambivalent about this; we don't want the string conversion of
   utostr, but using overload '+' mixed with string and integer arguments is
   sketchy. On the other hand, this particular usage is something of an idiom.

 - Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

Revert the ConstantInt constructors back to their 2.5 forms where possible, thanks to contexts-on-types.  More to come.

 - Yay for '-'s and simplifications!

__m128i b(__m128 a, __m128 b) { return a!=a | b!=b; }

_a:
	cmpordps	%xmm1, %xmm0

_b:
	cmpunordps	%xmm1, %xmm0
