  Log Message:
  -----------
  [BuildLibCalls/SimplifyLibCalls]  Fix attributes on created CallInst instructions.

- When emitting libcalls, do not only pass the calling convention from the
  function prototype but also the attributes.

- Do not pass attributes from e.g. libc memcpy to llvm.memcpy.
