[issue38015] inline function generates slightly inefficient machine code

[Greg Price]

(Just to help keep discussions together: some earlier discussion was on GH-15216 .)

Because is_small_int / IS_SMALL_INT is so small, there's not much cost in the source code to making it a macro (as GH-15710 did).

But I think it'd be a mistake to go a lot farther than that and convert significantly larger chunks of code like get_small_int to macros (as GH-15718 would), unless the payoff were really commensurate.  It'd be better to focus optimization efforts where profiling shows a lot of time is really being spent.
