[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][lld] --importTable flag only imports table if needed Before, --importTable forced the creation of an indirect function table, whether it was needed or not. Now it only imports a table if needed. Differential Revision: https://reviews.llvm.org/D96872

# CHECK-NEXT: Limits:
[WebAssembly] Rename WasmLimits::Initial to ::Minimum. NFC. This patch renames the "Initial" member of WasmLimits to the name used in the spec, "Minimum". In the core WebAssembly specification, the Limits data type has one required "min" member and one optional "max" member, indicating the minimum required size of the corresponding table or memory, and the maximum size, if any. Although the WebAssembly spec does instantiate locally-defined tables and memories with the initial size being equal to the minimum size, it can't impose such a requirement for imports. It doesn't make sense to require an initial size for a memory import, for example. The compiler can only sensibly express the minimum and maximum sizes. See https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limits for a related discussion that agrees that the right name of "initial" is "minimum" when querying the type of a table or memory from JavaScript. (Of course it still makes sense for JS to speak in terms of an initial size when it explicitly instantiates memories and tables.) Differential Revision: https://reviews.llvm.org/D99186
