Starting an incremental GC when it is not supported is not allowed but
trying to finalize one when it might be unknown whether it's supported
or not should be legal.
In such cases, finalization would immediately bail out since there is no
active gc.

`foo ## __LINE__` just emits foo__LINE__ because of how preprocessor
expansion works.

The typical solution for this is to use a CONCAT macro, but we in fact
already have a helper for what this is trying to solve,
UNIQUE_IDENTIFIER, so just use that instead.

A SafepointScope might need to block for a shared GC initiated from
another client isolate. This means that anytime we create a
SafepointScope a shared GC may run. This CL adds a DCHECK to ensure
AllowGarbageCollected::IsAllowed() holds for each SafepointScope.

So far this DCHECK was only run in the less likely event that a
SafepointScope actually runs a shared GC. Which is technically good
enough but it is easy to miss use cases of SafepointScope where this
does not hold.

Many callers already pass an int, so there is no point in storing as an
uint32_t internally. The style guide also recommends int as the general
data type for integers, even if it's statically known that only positive
values will occur.

In order to determine which module contains V8, v8windbg has been
looking for the known symbol v8::Script::Run. However, that symbol might
not be found if the function was inlined. To fix, we should instead
choose a symbol that is declared with V8_NOINLINE.

Using a map to store node states in Int64Lowering has proven slow.
Therefore, we change the data structure to a vector indexed by node ids.
