clang-p2996/polly/test/Isl/CodeGen/RuntimeDebugBuilder/combine_different_values.ll
Tobias Grosser 3717aa5ddb This reverts recent expression type changes 
The recent expression type changes still need more discussion, which will happen
on phabricator or on the mailing list. The precise list of commits reverted are:

- "Refactor division generation code"
- "[NFC] Generate runtime checks after the SCoP"
- "[FIX] Determine insertion point during SCEV expansion"
- "Look through IntToPtr & PtrToInt instructions"
- "Use minimal types for generated expressions"
- "Temporarily promote values to i64 again"
- "[NFC] Avoid unnecessary comparison for min/max expressions"
- "[Polly] Fix -Wunused-variable warnings (NFC)"
- "[NFC] Simplify min/max expression generation"
- "Simplify the type adjustment in the IslExprBuilder"

Some of them are just reverted as we would otherwise get conflicts. I will try
to re-commit them if possible.
