For consumers that aren't interested in *why* a `statSync` call failed,
allocating and throwing an exception is an unnecessary expense. This PR
adds an option that will cause it to return `undefined` in such cases
instead.
As a motivating example, the JavaScript & TypeScript language service
shared between Visual Studio and Visual Studio Code is stuck with
synchronous file IO for architectural and backward-compatibility
reasons. It frequently needs to speculatively check for the existence
of files and directories that may not exist (and cares about file vs
directory, so `existsSync` is insufficient), but ignores file system
entries it can't access, regardless of the reason.
Benchmarking the language service is difficult because it's so hard to
get good coverage of both code bases and user behaviors, but, as a
representative metric, we measured batch compilation of a few hundred
popular projects (by star count) from GitHub and found that, on average,
we saved about 1-2% of total compilation time. We speculate that the
savings could be even more significant in interactive (language service
or watch mode) scenarios, where the same (non-existent) files need to be
polled over and over again. It's not a huge improvement, but it's a
very small change and it will affect a lot of users (and CI runs).
For reference, our measurements were against `v12.x` (3637a061a at the
time) on an Ubuntu Server desktop with an SSD.

The existing text about processes not responding is unclear, at least to
me. Suggestions for clarification welcome, but I think the best thing
might be to state that the process may stop responding and leave it at
that. The explanantion (about asynchronous listeners) is not clear to
me. (Why would the fact that the listeners are asynchronous matter?) If
it's an unnecessary detail (as seems likely), let's remove it.

After conducting several benchmarks, I noticed performance losses of
5-10%. As OS X is not a performance critical platform, as already
mentioned by @bnoordhuis, I have removed the -no_pie flag at least for
this platform. I'd love to enable PIE for other platforms if the 5-10%
speed loss is not too high. I would be happy to hear your opinion on
this.

Original commit message:
[mac] Set MAP_JIT only when necessary
This is a "minimal" change to achieve the required goal: seeing that
there is only one place where we need to indicate that memory should
be reserved with MAP_JIT, we can add a value to the Permissions enum
instead of adding a second, orthogonal parameter.
That way we avoid changing public API functions, which makes this CL
easier to undo once we have platform-independent w^x in Wasm.

Fix alloc/dealloc size mismatch for v8::BackingStore
On newer compilers the {operator delete} with explicit {size_t}
argument would be instantiated for {v8::BackingStore} and used
in the destructor of {std::unique_ptr<v8::BackingStore>}. The {size_t}
argument is wrong though, since the pointer actually points
to a {v8::internal::BackingStore} object.
The solution is to explicitly provide a {operator delete}, preventing
an implicitly generated {size_t} operator.

Original commit message:
[heap-profiler] Fix crash when a snapshot deleted while taking one
Fix a crash/hang that occurred when deleting a snapshot during the
GC that is part of taking another one.
Specifically, when deleting the only other snapshot in such
a situation, the `v8::HeapSnapshot::Delete()` method sees that there
is only one (complete) snapshot at that point, and decides that it is
okay to perform “delete all snapshots” instead of just deleting
the requested one. That resets the internal string lookup table
of the heap profiler, but the new snapshot that is currently in
progress still holds references to the old string lookup table,
leading to a use-after-free segfault or infinite loop.
Fix this by guarding against resetting the string table while
another heap snapshot is being taken, and add a test that would
crash before this fix.
This can be triggered in Node.js by repeatedly calling
`v8.getHeapSnapshot()`, which provides heap snapshots as weakly
held host objects.
