As you mentioned, unsigned conversions to int and long int both fail to
vectorize.  However, signed conversions to long int still fail, while they
succeed for signed conversions to int.

I should note that the computer I ran these last tests on is a Phenom II.

Apologies if I'm mistaken, but I believe the intrinsic

__builtin_ia32_cvttsd2si64

should do the conversion to a signed long on my platform.
