Previously GetSharedFunctionInfoForStreamedScript didn't either check the
compilation cache or put the result of compilation into the compilation
cache. This would mean future compiles would need to re-parse / compile
the same script even if the isolate had already seen it. This CL
fixes this.
Also refactors the compilation pipelines to ensure we call debug->OnAfterCompile()
for all script compiles even when loading from a cache.

The "FreezeWasmLazyCompilation" runtime function can only be invoked if

must be skipped. The other tests are not affected by this, thus un-skip

Original Commit Message:
The original CL introduced a test which uses a random number generator.
I disable the test for now, which is okay because this CL adds to a
work-in-progress feature anyways, and I will fix the problem in another
CL.
Original description:
Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.
So far, only ia32 and x64 are implemented.

In order to test that we don't repeatedly go through the
WasmCompileLazy runtime function, add a flag to the
LazyCompilationOrchestrator to "freeze" it, i.e. disallow any further
lazy compilation.
In tests, use this flag to first call a method, then freeze lazy
compilation, then call the method again to assert that no further lazy
compilation is triggered.
This test currently fails with --wasm-jit-to-native, so disable it for
that variant.
