Skip reloads and copies in `gcIsWriteBarrierCandidate`.

The change is actually in `gcWriteBarrierFormFromTargetAddress`. Because copies/reloads
may be placed inside of address-forming trees and because such operations are
transparent w.r.t. the GC-ness of their operand, these nodes should be skipped during
the check for write barriers.

Fixes dotnet/coreclr#5484.
