Problem:
PCM file includes references to all module maps used in compilation which created PCM. This problem leads to PCM-rebuilds in distributed compilations as some module maps could be missing in isolated compilation. (For example in our distributed build system we create a temp folder for every compilation with only modules and headers that are needed for that particular command).

Solution:
Add only affecting module map files to a PCM-file.

Previously, in case there was only one `Optional` operand/result within
the list, we would always return `None` from the accessor, e.g., for a
single optional result we would generate:

```
return self.operation.results[0] if len(self.operation.results) > 1 else None
```

But what we really want is to return `None` only if the length of
`results` is smaller than the total number of element groups (i.e.,
the optional operand/result is in fact missing).

This commit also renames a few local variables in the generator to make
the distinction between `isVariadic()` and `isVariableLength()` a bit
more clear.

NamedAttribute is currently represented as an std::pair, but this

converts it to a class, with better accessors (getName/getValue)

Also, mark these tests as compile-only. They actually are safe to run — notice that
the code "runs" at constexpr-time in C++20, without error — because both of the
input ranges are entirely filled with nullptr, so no matter how you shuffle the
elements, they remain sorted and partitioned and heapified and everything.
But there's no real reason to run them at runtime, so let's just avoid the distraction.

Test cases that fail in trunk right now are commented out with `TODO FIXME`.

std::atomic is, for the most part, just a thin veneer on top of compiler
builtins. Hence, it should be available even when threads are not available
on the system, and in fact there has been requests for such support.

This patch:
- Moves __libcpp_thread_poll_with_backoff to its own header so it can
  be used in <atomic> when threads are disabled.
- Adds a dummy backoff policy for atomic polling that doesn't know about
  threads.
- Adjusts the <atomic> feature-test macros so they are provided even when
  threads are disabled.
- Runs the <atomic> tests when threads are disabled.

pthread_join needs to map pthread_t of the joined thread to our Tid.
Currently we do this with linear search over all threads.
This has quadratic complexity and becomes much worse with the new
tsan runtime, which memorizes all threads that ever existed.

To resolve this add a hash map of live threads only (that are still
associated with pthread_t) and use it for the mapping.

With the new tsan runtime some programs spent 1/3 of time in this mapping.
After this change the mapping disappears from profiles.

Depends on D113996.

The `--noexecstack` assembler option is unneeded because AsmPrinter.cpp
