[Decompilation] [th04/th05] vector1_at(), vector2_at()
Almost undecompilable, until you remember that you can inhibit the optimization of keeping a function parameter in a register by having an `inline` function take a reference. Yet another function that wouldn't have decompiled that nicely if we had restricted us to C… Part of P0136, funded by [Anonymous].
