Maksim Panchenko c823220116 [BOLT] Better check for compiler de-virtualization bug

Summary:
The existing check for compiler de-virtualization bug was not working
when the relocation reference did not fall on a function boundary.
As a result, we were falsely detecting "unmarked object in code".

When running the check, the address could be arbitrary, except it
shouldn't match any existing function. Additionally, check that there's
a proper reference to the de-virtualized callee to avoid false
positives.

(cherry picked from FBD17433887)
