See bug#12541; removing the "inline" helped performance slightly there.

More generally, these days "inline" is mostly a noise word for static
functions, just as "register" is a noise word for locals.  Modern
compilers inline static functions pretty well without "inline", just
as they allocate registers pretty well without "register", and it
saves maintenance hassle if developers don't have to waste their
time reading the "inline" noise and worrying about whether the
"inline" should be there.
Instead, we get reports of emacs taking 3x longer to do something after "inline noise" is removed, leading some to wonder whether "inline" should be there after all...

(doesn't mean you want force the compiler to inline everything, but going to either extreme is going to hurt performance)
