Saúl Cabrera 4f47f3ecaf winch: Add a subset of known libcalls and improve call emission (#7228 ) * winch: Add known a subset of known libcalls and improve call emission This change is a follow up to: - https://github.com/bytecodealliance/wasmtime/pull/7155 - https://github.com/bytecodealliance/wasmtime/pull/7035 One of the objectives of this change is to make it easy to emit function calls at the MacroAssembler layer, for cases in which it's challenging to know ahead-of-time if a particular functionality can be achieved natively (e.g. rounding and SSE4.2). The original implementation of function call emission, made this objective difficult to achieve and it was also difficult to reason about. I decided to simplify the overall approach to function calls as part of this PR; in essence, the `call` module now exposes a single function `FnCall::emit` which is reponsible of gathtering the dependencies and orchestrating the emission of the call. This new approach deliberately avoids holding any state regarding the function call for simplicity. This change also standardizes the usage of `Callee` as the main entrypoint for function call emission, as of this change 4 `Callee` types exist (`Local`, `Builtin`, `Import`, `FuncRef`), each callee kind is mappable to a `CalleeKind` which is the materialized version of a callee which Cranelift understands. This change also moves the creation of the `BuiltinFunctions` to the `ISA` level given that they can be safely used accross multiple function compilations. Finally, this change also introduces support for some of the "well-known" libcalls and hooks those libcalls at the `MacroAssembler::float_round` callsite. -- prtest:full * Review comments * Remove unnecessary `into_iter` * Fix remaining lifetime parameter names		1 year ago
