  [Linker] Remove nocallback attribute while linking

GCC's leaf attribute is lowered to LLVM IR nocallback attribute.
Clang conservatively treats this function attribute as a hint on the
module level, and removes it while linking modules. More context can
be found in: https://reviews.llvm.org/D131628.
