Manoj Gupta 9d83ce9043 [Inline] Copy "null-pointer-is-valid" attribute in caller. ...

Summary:
Normally, inling does not happen if caller does not have
"null-pointer-is-valid"="true" attibute but callee has it.

However, alwaysinline may force callee to be inlined.
In this case, if the caller has the "null-pointer-is-valid"="true"
attribute, copy the attribute to caller.
