Subject: [PATCH] Outline X86 autoupgrade patterns
Outlining these patterns has a significant impact on the overall stack
frame size of llvm::UpgradeIntrinsicCall. This is helpful for scenarios
where compilation threads are stack-constrained. The overall impact is
low when using clang as the host compiler, but very pronounced when using
MSVC 2022 with release builds.
Clang: 1,624 -> 824 bytes
MSVC: 23,560 -> 6,120 bytes
