[PATCH] D152550: [Constant Hoisting]: Hoist Constant GEP Expressions.

hassnaa-arm added a comment.

- Avoid hoisting in following cases:
  - The cost of the const expr is 'free' for the target.
  - The expr can be folded into a legal addressing mode for the target.
  - The expr has only single use, and it's not inside a loop.
- Now there are no regressions.
