  -----------
  [LangRef] Correct documentation for `roundeven` (#125452)

Langref for `roundeven` implies that the C standard function `roundeven`
may raise floating point exceptions. However, this is not correct; C23
does not mention exceptions for `roundeven`, and per [1] `FE_INEXACT` is
never raised.

Clarify that LLVM's `roundeven` behaves the same.
