Cool, thanks. LGTM, two nits.



================
Comment at: llvm/utils/UpdateTestChecks/common.py:532
+      and _prefix_filecheck_ir_name:
+      var = _prefix_filecheck_ir_name + var
   var = var.replace('.', '_')
----------------
Move the re.match into a helper (also used below), maybe: `may_clash_with_default_check_prefix_name(check_prefix, var)`


================
Comment at: llvm/utils/UpdateTestChecks/common.py:563
+        if nameless_value.check_prefix and re.match(r'^' + nameless_value.check_prefix + r'[0-9]+?$', var, re.IGNORECASE) \
+          and not _prefix_filecheck_ir_name:
+          warn("Change IR value name '%s' or use -prefix-ir-filecheck-name to prevent possible conflict"
----------------
I would not add the `and not _prefix_filecheck...` stuff here because if the other condition holds a warning seems appropriate, maybe the prefix was chosen pooreley, etc.
