Zarko Todorovski a61b202d4e [Clang][Sema][AIX][PowerPC] Emit byval alignment warning only when struct is passed to a function ...

Previous warning went on whenever a struct with a struct member with alignment => 16
was declared. This led to too many false positives and led to diagnostic lit failures
due to it being emitted too frequently. Only emit the warning when such a struct and
that struct contains a member that has an alignment of 16 bytes is passed to a caller
function since this is where the potential binary compatibility issue with XL 16.1.0
and older exists.
