[PATCH] D66862: Make lround builtin constexpr (and others)

This revision now requires changes to proceed.

Craig topper pointed out to me that constexpr cannot throw exceptions, and at least the rints can raise some exceptions, which aren't allowed in Constexpr.  The round functions similarly hit unspecified behavior, so we need to match that behavior.
