Clemens Hammacher 6a36b2a040 [wasm] [cleanup] Remove CompileInstantiateWasmModuleForTesting
This is a testing-only function, which is semantically equivalent to a
SyncCompile followed by SyncInstantiate.
We add a new SyncCompileAndInstantiate function to do those two steps
in one go, and use this method instead.
For AsmJs modules, a new testing function CompileAndRunAsmWasmModule is
introduced.

This is part of our effort to reduce the number of special paths for
testing. It is connected with
https://chromium-review.googlesource.com/529210, but should not
conflict with it.
After landing both CLs, we can later also get rid of
InstantiateModuleForTesting.
