llvm/utils/UpdateTestChecks
David Greene 131e1c17a8 Allow update_test_checks.py to not scrub names.
Add a --preserve-names option to tell the script not to replace IR names.
Sometimes tests want those names.  For example if a test is looking for a
modification to an existing instruction we'll want to make the names.
