Jingyue Wu ab0a70d3a3 Remove the user-count threshold when analyzing read attributes ... Summary: This threshold limited FunctionAttrs ability to prove arguments to be read-only. In NVPTX, a specialized instruction ld.global.nc can be used to load memory with non-coherent texture cache. We notice that in SHOC [1] benchmark, some function arguments are not marked with readonly because FunctionAttrs reaches a hardcoded threshold when analysis uses. Removing this threshold won't cause significant regression in compilation time, because the worst-case time complexity of the algorithm is still O(# of instructions) for each parameter.
