some hacky checks for common errors

They're not really baked into the regular compilation process; I have to
remember to run them if I see strange behavior.

+# We still rely exclusively on linux/bootstrap/bootstrap for some static
+# checks on bare SubX code that aren't implemented yet in the self-hosted
+# translator phases.
+#
+# However, boot.subx uses instructions that bootstrap doesn't recognize. So we
+# won't check it.
