That's probably because of the change below. SSE packs can currently
only be compiled as static constants, and this really should be the
way they are handled: that negation operation is really supposed
to compile down to one XORPS instruction.
As an alternative, if there is a way to fuse the constant with
the unboxing operation, the unboxed value can probably be represented
as an expression using a couple of C intrinsic functions.
