compiler: Use FramePointer::NonLeaf for Apples

workingjubilee · workingjubilee · commit 6822314625d8 · 2025-05-30T14:42:18.000-07:00
All Apple targets stop overriding this configuration and instead use the
default base of FramePointer::NonLeaf, which means some Apples will have
less frame pointers in leaf functions.
