-// Note that there is a hardware instruction, fildll, that does most of what
-// this function needs to do.  However, because of our ia32 ABI, it will take
-// a write-small read-large stall, so the software implementation here is
-// actually several cycles faster.
-
-// This is a branch-free implementation.  A branchy implementation might be
-// faster for the common case if you know something a priori about the input
-// distribution.
