It turns out that `native` is indeed an unknown CPU and we have to perform a mapping to an actual CPU name, but this mapping is only performed in one location rather than all locations we inform LLVM about the target CPU. This commit centralizes the mapping of `native` to LLVM's value of the native CPU, ensuring that all locations we inform LLVM about the `target-cpu` it's never `native`.

Tracked by #52090 this new directive in the `#[link]` attribute is used to configured the module name that the imports are listed with. The WebAssembly specification indicates two utf-8 names are associated with all imported items, one for the module the item comes from and one for the item itself. The item itself is configurable in Rust via its identifier or `#[link_name = "..."]`, but the module name was previously not configurable and defaulted to `"env"`. This commit ensures that this is also configurable.

The LLD submodule is updated in tandem as well as compiler-builtins. Along the way support was also added for LLVM 7's new features. This primarily includes the support for custom section concatenation natively in LLD so we now add wasm custom sections in LLVM IR rather than having custom support in rustc itself for doing so. Some other miscellaneous changes are: * We now pass `--gc-sections` to `wasm-ld` * The optimization level is now passed to `wasm-ld` * A `--stack-first` option is passed to LLD to have stack overflow always cause a trap instead of corrupting static data * The wasm target for LLVM switched to `wasm32-unknown-unknown`. * The syntax for aligned pointers has changed in LLVM IR and tests are updated to reflect this. * The `thumbv6m-none-eabi` target is disabled due to an [LLVM bug][llbug] Nowadays we've been mostly only upgrading whenever there's a major release of LLVM but enough changes have been happening on the wasm target that there's been growing motivation for quite some time now to upgrade out version of LLD. To upgrade LLD, however, we need to upgrade LLVM to avoid needing to build yet another version of LLVM on the builders. The revision of LLVM in use here is arbitrarily chosen. We will likely need to continue to update it over time if and when we discover bugs. Once LLVM 7 is fully released we can switch to that channel as well.
