997: Compiler tests r=MarkMcCaskey a=syrusakbary
# Description
This PR simplifies the testing part, making `wasmer_runtime_core` the one responsible for picking the default backend.
This makes tests much simpler, and reliable when trying to run in different backends (this PR solves an issue when trying to run wasitests on ARM machines).

995: fix(runtime-core) Remove a panic when generating globals with a corrupted module r=syrusakbary a=Hywan
Fix#979.
When we try to get a global that doesn't exist, a panic is
generated. This patch skips such panic and let a proper error be
generated.
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." }])
```

Before this patch:
```
$ cargo run -- run panic_index_oob_all_backends.wasm
Error: ExportNotFound { name: "main" }
```
With this patch:

$ 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.
