[IR] adjust assert when replacing undef elements in vector constant
As noted in follow-up to: rGa1e8ad4f2fa7
It's not safe to assume that an element of the constant is always
non-null. It's definitely not an expected case for the current
instcombine user, but that may not hold if this function is eventually
called from arbitrary places.

[ARM] Use isFMAFasterThanFMulAndFAdd for MVE
The Arm backend will usually return false for
isFMAFasterThanFMulAndFAdd, where both the fused VFMA.f32 and a
non-fused VMLA.f32 are usually available for scalar code. For MVE we
don't have the non-fused version though. It makes more sense for
isFMAFasterThanFMulAndFAdd to return true, allowing us to simplify some
of the existing ISel patterns.
The tests here are that non of the existing tests failed, and so we are
still selecting VFMA and VFMS. The one test that changed shows we can
now select from fast math flags, as opposed to just relying on the
isFMADLegalForFAddFSub option.
