Before this patch:
```
$ cargo run -- run panic_index_oob_all_backends.wasm
Error: ExportNotFound { name: "main" }
```
With this patch:
```sh
$ cargo run -- run panic_index_oob_all_backends.wasm
Error: Can't instantiate module: LinkError([Generic { message: "Trying to read the `0` global that isn\'t properly initialized." }])
```
Fix https://github.com/wasmerio/wasmer/issues/979.
When we try to get a global that doesn't exist, a panic is
generated. This patch just skip that path, and let a proper error be
generated later.
With this patch, we get:
```sh
$ cargo run -- run panic_index_oob_all_backends.wasm
Error: ExportNotFound { name: "main" }
```
which is kind of the expected behavior in such situation.
977: fix(runtime-core) Remove unnecessary implementation of `WasmTypeList` r=Hywan a=Hywan
The unit tests `test_func_arity_*` covers all possibilities, from 0 to
12. Removing this specific implementation of `WasmTypeList` for `(A,)`
doesn't break the test cases.
Also, the `impl_traits!` macro already implement `WasmTypeList` for
`(A,)` with `impl_traits!([transparent] S1, A)`. It's not clear why
`rustc` doesn't detect that though.

By exposing the target information through `CompilerConfig`,
compiler(only LLVM at the moment) could create a machine with
different CPU feature flags other than current host, which makes it
capable to "cross compile" to some degree.
