We need 2 new pragmas with the same syntax as `pragma(inline, xxx)`:
1. `pragma(fusedMath)` allows fused mul-add, mul-sub, div-add, div-sub
operations.
2. `pragma(fastMath)` equivalents to [1]. This pragma can be used to allow
extended precision.
The LDC fastmath bothers me a lot. It throws away proper NaN and infinity
handling, and throws away precision by allowing reciprocal and algebraic
transformations. As I've said before, correctness should be first, not speed,
and fastmath has nothing to do with this thread.
I don't know what the point of fusedMath is.
