  [utils] change update_test_checks.py use of 'TMP' value names

As discussed in PR45951:
https://bugs.llvm.org/show_bug.cgi?id=45951

There's a potential name collision between update_test_checks.py and -instnamer
and/or manually-generated IR test files because all of them try to use the
variable name that should never be used: "tmp".

This patch proposes to reduce the odds of collision and adds a warning if we
detect the problem. This will cause regression test churn when regenerating
CHECK lines on existing files.
