When exporting `shared-library` in profile log, additionally export a
slide offset. This is required to parse profile logs generated on
systems with ASLR (OS X), otherwise it is impossible to assign C++
symbol names to their addresses in the log.

It is unsound to look at the types in the TurboFan graphs after the
representation selection (and early optimization) phases, because
(a) the remaining phases (might) run concurrently, and
(b) the types may not be accurate (or even correct) after
representation selection due to the way we deal with
truncations.
So in Debug builds we now explicitly remove all types from the nodes
right after we uninstall the Typer decorator from the Graph, so any
further attempt to access the Type of a Node will lead to a crash (again
in Debug only for now).

Further refactor the pipeline to even run the first scheduler (part of
the effect control linearization) concurrently. This temporarily
disables most of the write barrier elimination, but we will get back to
that later.
Drive-by-fix: Remove the dead code from ChangeLowering, and stack
allocate the Typer in the pipeline. Also migrate the AllocateStub to a
native code builtin, so that we have the code object + a handle to it
available all the time.

I introduced a new flag, --wasm-parallel-compilation, which turns on
parallel compilation of wasm modules. If parallel compilation is turned
on, then the compilation of wasm functions is split into three phases,
initialization, execution, and finalization. The execution phase is the
phase which is going to contain all the code that can be executed in
parallel. At the moment the execution phase is still empty.

Instead of replacing the array with an empty one after resuming, overwrite

This will simplify the work to be done by the bytecode graphbuilder and
