If a function f being considered for inlining calls one of its parameters, reduce the normal cost of that call (57) to 17 to increase the chance that f will be inlined and (with luck) that parameter will be revealed as a constant function (which unblocks escape analysis) or perhaps even be inlined. The least-change value for that was still effective for iter_test benchmarks was 32; however tests showed no particular harm even when reduced as low as 7, and there have been reports of other performance problems with rangefunc overheads and so I picked a middling number in hopes of warding off such reports.
