OK, then we need a third pragma,`pragma(ieeeRound)`. But
`pragma(fusedMath)`
and `pragma(fastMath)` should be presented too.

It allows a compiler to replace two arithmetic operations with
single composed one, see AVX2 (FMA3 for intel and FMA4 for
AMD) instruction set.
No pragmas tied to a specific architecture should be allowed in
the language spec, please.
Then probably Mir will drop all compilers, but LDC
LLVM is tied for real world, so we can tied D for real world too.
If a compiler can not implement optimization pragma, then this
pragma can be just ignored by the compiler.
