[InstCombine] Use IRBuilder in freeze pushing transform (PR55619)

Use IRBuilder so that the newly created freeze instructions
automatically gets inserted back into the IC worklist.

The changed worklist processing order leads to some cosmetic
differences in tests.

Fixes https://github.com/llvm/llvm-project/issues/55619.
