[llvm] Use computeConstantRange to improve llvm.objectsize computation (#114673)
Using LazyValueInfo, it is possible to compute valuable information for
allocation functions, GEP and alloca, even in the presence of dynamic
information.
llvm.objectsize plays an important role in _FORTIFY_SOURCE definitions,
so improving its diagnostic in turns improves the security of compiled
application.
As a side note, as a result of recent optimization improvements, clang
no longer passes
https://github.com/serge-sans-paille/builtin_object_size-test-suite This
commit restores the situation and greatly improves the scope of code
handled by the static version of __builtin_object_size.
