This patch introduces a new abstract attributor instance that propagates assumption information from functions. Conceptually, if a function is only called by functions that have certain assumptions, then we can apply the same assumptions to that function. This problem is similar to calculating the dominator set, but the assumptions are merged instead of nodes. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D111054
