Fix handling of thunks in ipa-modref
Thunks are not transparent for ipa-modref summary since it cares about offsets
from pointer parameters and also for virtual thunk about the read from memory
in there. We however use function_or_virtual_thunk_symbol to get the summary
that may lead to wrong code (and does in two testsuite testcases with patch
I am working on). This is a first aid fix that is bacportable to gcc 11.
We could easily produce summary for thunk on demand. I will look into it
incrementally. It is not very important since we usually inline the thunk when
we devirutalize...
Bootstrapped/regtested x86_64-linux, will commit it shortly.
