[update_llc_test_checks][VE] Add baseline test for PIC function regex

[arichardson]

Summary

While working on https://reviews.llvm.org/D131429, I got a test diff in
one of the VE tests and running update_llc_test_checks.py deleted all the
code for that function. This is a baseline test for this bug (incorrect
regex for VE when .Lfoo$local symbols are used).

This patch itself looks fine although I'm not sure what the point of this patch is.

Maybe the purpose of this patch is related to D131431. LGTM.
