The commit r308100 updated WebAssembly tests for r308025. In one case it merely made the test more resilient but in another case it made a substantive update. Because r308025 was reverted in r308271, these changes to the test also need to be reverted. They should be folded into the recommit of r308025 when it is ready. llvm-svn: 308273
