[PATCH] D75993: [Target][ARM] Improvements to the VPT Block Insertion Pass

[Pierre van Houtryve via Phabricator via llvm-commits]

Pierre-vh updated this revision to Diff 250230.
Pierre-vh added a comment.

Here is the refactored version of this patch. I tried to make the structure a bit cleaner and easier to work on.

- Made the function that expands the block masks more generic, it can now add one or more T/Es to any mask.
- Split the code into multiple functions

Note that I still need to add tests for the new supported cases, I'll try to add them later today or on Monday.
