This patch fixes a failure in TestFunctionStarts.py that appeared
following a change of implementation for synthetic symbol names:
https://reviews.llvm.org/D105160
The failure is caused because the previously mentioned patch removes the
object file basename from the generated synthetic symbol names to allow
them to be shared in the constant string pool.
Hence, that last check is not necessary anymore.
