In my previous CL, I completely disabled the processing of inlining stacks
when generating code comments. This CL restores the feature at least for
runs without concurrent recompilation.
In other words, if you use --code-comments and want to see nice source positions,
you must also use --no-concurrent-recompilation.

In debug mode (SLOW_DCHECK), Handle<T>::cast accesses the object to

This is the x64 implementation of the CL
https://codereview.chromium.org/2763593002
Original message:
[wasm][arm] Add an additional stack check for functions with big frames.
Stack overflow checks are typically implemented as part of the TurboFan
graph of a function. This means that the stack check code is executed
after frame construction. When a frame is too big, though, there may not
be enough space on the stack anymore to throw the stack overflow
exception after frame construction. With this CL we do an additional
stack check before frame construction for functions with big frames.
As discussed offline with mstarzinger, I do this change currently only
for WebAssembly.
This CL contains only the changes for arm. I will do the other platforms
in separate CLs.

Storing global handles in the interpreter is dangerous, because the
global handles are strong roots into the heap. The interpreter itself is
referenced from the heap via a Managed. Hence the interpreter keeps the
instance alive, while the instance keeps the Managed alive. So the GC
will never collect them.
This CL refactors this to only store the handle to the instance object
while executing in the interpreter, and clearing it when returning.
It also removes the cache of import wrappers, as it should not be

There is one slight semantical change: Called with kMinInt, it
previously returned true, because the argument was implicitly casted to
an unsigned. It's now (correctly) returning false, so I had to add
special handlings of kMinInt in machine-operator-reducer before calling
IsPowerOfTwo on that value.

The instruction sequence consumes a significant amount of memory, so it
should be deallocated as early as possible. This CL separates the zone
which is used by the code generator from the zone which is used by the
instruction selector. Thereby we can delete the instruction selector
zone, which contains the instruction sequence, already after
AssembleCode, and not only after FinalizeCode.
For WebAssembly this means that the instruction sequence gets deleted
on the background tasks already and does not stay alive until the
main threads deletes it.

The problem popped up when passing the constants by reference
(https://chromium-review.googlesource.com/c/565141).
It's a bit ugly, but, the C++11 standard requires a definition
additionally to the existing declaration in the body of the class:
9.4.2/4: If a static data member is of const literal type, its
declaration in the class definition can specify a
brace-or-equal-initializer in which every initializer-clause that is
an assignment-expression is a constant expression. A static data
member of literal type can be declared in the class definition with
the constexpr specifier; if so, its declaration shall specify a
brace-or-equal-initializer in which every initializer-clause that i
an assignment-expression is a constant expression. [Note: In both
these cases, the member may appear in constant expressions. — end
note] The member shall still be defined in a namespace scope if it is
odr-used (3.2) in the program and the namespace scope definition shall
not contain an initializer.
Drive-by: Make the static constants constexpr.
