This patch makes a small enhancement to call result scoring, to make it more independent of param value heuristics. For this pair of functions: func caller() { v := callee(10) <<-- this callsite if v > 101 { ... } } func callee(x int) { if x < 0 { G = 1 } return 9 } The score for the specified call site above would be adjusted only once, for the "pass constant to parameter that feeds 'if' statement" heuristic, which didn't reflect the fact that doing the inline enables not one but two specific deadcode opportunities (first for the code inside the inlined routine body, then for the "if" downstream of the inlined call). This patch changes the call result scoring machinery to use a separate set of mask bits, so that we can more accurately handle the case above.
