[lld][WebAssembly] Convert some lld tests to assembly When we originally wrote these tests we didn't have a stable and fleshed out assembly format. Now we do so we should prefer that over llvm ir for lld tests to avoid including more part of llvm than necessary in order to run the test. This change converts just 30 out of about 130 test files. More to come when I have some more time. Differential Revision: https://reviews.llvm.org/D80361

[WebAssembly] Don't generate invalid modules when function signatures mismatch Previously we could emit a warning and generate a potentially invalid wasm module (due to call sites and functions having conflicting signatures). Now, rather than create invalid binaries we handle such cases by creating stub functions containing unreachable, effectively turning these into runtime errors rather than validation failures.

[lld][WebAssembly] Use a more meaningful name for stub functions When we generate these stub functions on signature mismatches give them a more meaningful name so that when people see this in stack traces is gives a clue as the what is going on.
