[spirv-writer] Fix atomics after discard

Run DemoteToHelper before any SPIR-V transforms, as core transforms
are not aware of the potential side effects of non-core instructions.

Added an assertion in DemoteToHelper to capture this ordering
requirement with a TODO to use the validator to catch it instead.
