Alexis Laferrière 39c3fc01a8 [Serialization] Restrict loading all swiftmodules by compiler tag ...

Swiftmodule loading was previously restricted by compiler tag only for
resilient modules. This left room for resilient modules with a corrupted
control block to pass as non-resilient modules.

Apply the same check for non-resilient modules (so all modules) when
read from a tagged compiler.
