Nick Fitzgerald 47fa1ad6a8 Rework bounds checking for atomic operations (#5239)
Before, we would do a `heap_addr` to translate the given Wasm memory address
into a native memory address and pass it into the libcall that implemented the
atomic operation, which would then treat the address as a Wasm memory address
and pass it to `validate_atomic_addr` to be bounds checked a second time. This
is a bit nonsensical, as we are validating a native memory address as if it were
a Wasm memory address.

Now, we no longer do a `heap_addr` to translate the Wasm memory address to a
native memory address. Instead, we pass the Wasm memory address to the libcall,
and the libcall is responsible for doing the bounds check (by calling
`validate_atomic_addr` with the correct type of memory address now).

This crate performs the translation from a wasm module in binary format to the in-memory form of the Cranelift IR.
