A previous patch has already changed getInstructionCost to return an InstructionCost type. This patch changes the other various getXXXCost functions to return an InstructionCost too. This is a non-functional change - I've added a few asserts that the costs are valid in places where we're selecting between vector call and intrinsic costs. However, since we don't yet return invalid costs from any of the TTI implementations these asserts should not fire. See this patch for the introduction of the type: https://reviews.llvm.org/D91174 See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2020-November/146408.html Differential Revision: https://reviews.llvm.org/D94065
