Nick Fitzgerald 18fabd7700 bench-api: Allow multiple instantiations per compilation We used to allow at most one instantiation per compilation, but there is no fundamental reason why that should be the case. Allowing multiple instantiations per compilation allows us to, for example, benchmark repeated instantiation within Wasmtime's pooling allocator. This additionally switches to using host functions for WASI and for `bench_{start,end}` rather than defining them on the linker, this way we can use a new store for every instantiation and don't need to keep other instances alive when instantiating new instances. Finally, we switch all timing to be done through callback functions, rather than having the bench API caller implicitly start/end timers around bench API calls. This allows us to more precisely measure phases and exclude things like file I/O performed when creating a WASI context.		4 years ago
