FP operations listed in FloatingPointOps.def are now lowered to DAG in the same
way as constrained intrinsics, using special DAG nodes like STRICT_NEARBYINT.
This is a temporary solution. Existing nodes like S

Constrained intrinsics are treated as regular intrinsicss from the perspective
of FP operand bundle mechanism, meaning they can have FP operand bundles. The
FP bundle API functions will report properties based

Two new operands are now supported in the "fp.control" operand bundle:
* "denorm.in=xxx" - specifies the inpot denormal mode.
* "denorm.out=xxx" - specifies the output denormal mode.

Rounding mode is a parameter of a floating-point operation, its effect does not
depend on the fact that it comes from a register or is specified as an
immediate value. Implementing them differently does not look like a good
solution.

This attribute is needed only for validation of FP operand bundles, to check if
a call may have such bundles. It addresses the concern that a call should have
FP bundles only when they make sense for the called function (e.g.

Just as with #100378 the changes in tests demonstrates that the produced code
becomes worse. In what cases this patch makes improvement? Can it be limited to
such cases?
