Git commit 34323ab08e6eed2caff556ecdeae20053cbaaae7 by GitHub (on behalf of Jonas Devlieghere) on 07/08/2026 at 05:21..
[lldb] Fix the lazy initialization of Module's global collections (NFC) (#214630)

Both collections were initialized with a check-then-set on a null
pointer, which is race-y. We can achieve the same thing by initializing
the pointer with the allocation, while retaining the leak.

[Target] Add shouldDefaultToNewPM flag

This will allow for tools like clang/flang/llc to default to the NewPM
for targets that request it.

Future patches will update clang/llc and flip it for targets that have
been fully ported but shouldn't have a large blast radius (like Lanai
and MSP430).
