[NFC][InstCombine] Let update_test_checks change variable names of integer-round-up-pow2-allignment.ll

[emgullufsen]

Summary

Run update_test_checks.py against integer-round-up-pow2-allignment.ll,
letting it choose different names for variables.

Separating NFC changes here from forthcoming changes

[emgullufsen]

These NFC variable name changes were in anticipation of functional changes from D131142, but since that patch no longer changes the test in question (llvm/test/Transforms/InstCombine/integer-round-up-pow2-alignment.ll), these NFC changes made by update_test_checks.py separated out here probably can be abandoned.

[spatel]

I'd leave this file alone if there are no planned changes from the other patch. We can update as needed whenever real changes are made here.
