I agree with the revert - we'd need lots of commits like this:
b7232dafe69eb04c14217 
<https://reviews.llvm.org/rGb7232dafe69eb04c1421743e4bd779d6ff3853be> (cc 
@arsenm)

Another possibility to fix this with less churn:
Add a warning during (re-)generation for any test where the CHECK-LABEL could 
be going wrong. So scan the file for a call to a function name that is also 
defined in that file?
We already have a warning like that for variables named `%tmp`. So if a test 
file contains the potentially buggy construct, then warn the user that they 
should regenerate with "--function-signature" to be safe.
