__assume on MSVC passes hints to the compiler for optimization, it
assumes the expression is always true. So that a function like this:

int f(int x)
  __assume(x == 0)
  return x;

is optimized by the compiler and just returns 0, without checking for x.
It really seems an interesting opportunity for using already
assertions for optimizations.
The original thread is "BOOST_ASSERT and __assume on MSVC"
