ci: Start running wasm32 tests on Travis This commit allocates a builder to running wasm32 tests on Travis. Not all test suites pass right now so this is starting out with just the run-pass and the libcore test suites. This'll hopefully give us a pretty broad set of coverage for integration in rustc itself as well as a somewhat broad coverage of the llvm backend itself through integration/unit tests. 2017-11-26 10:39:16 -08:00			`static mut a: i32;`
Support foreign 'static mut' variables as well 2013-06-21 22:46:27 -07:00			`}`
