[PATCH] D156113: [CodeGen] Store call frame size in MachineBasicBlock

foad added a comment.

This is a rework of D154281 <https://reviews.llvm.org/D154281>:

- Fixes the ARM bug reported by @olista01. ARM frame index elimination was relying on SPAdj being passed in as 0 if call frame pseudos were eliminated early (the canSimplifyCallFramePseudos case).
- Stores "call frame size" instead of "SP adjustment". This feels a bit more canonical and maps directly to the call frame size stored in call frame setup/destroy pseudos.
- Adds machine verification and a bunch of fixes that that required.
