It is still needed. This patch depends on D74729 <https://reviews.llvm.org/D74729>. Next steps, like support in frontend (as fesetround) and lowering on other platforms make sense only after destiny of these patches will be determined.

The motivation for this work is implementation of a pragma that would set/restore rounding mode without need to call fesetround.
