emacs-geiser/geiser@aa26163 -> emacs-geiser/geiser@c5a9aae
With emacs-geiser/geiser@c5a9aae, geiser-impl--add-to-alist is now
autoloaded. This fixes#4863 by preventing void-function errors at
startup or 'doom sync'-time.
But this presents a new problem: geiser-impl is guaranteed to be
needlessly loaded at startup, the first time geiser-impl--add-to-list is
called among, say, geiser-chez's package autoloads. To get around this I
forcibly redefine it as an inline-able function (with defsubst) and
shove this new definition into Doom's autoloads file (where it will
appear before package autoloads).
Since Doom byte-compiles its autoloads file (containing concatenated
autoloads from all doom modules and packages), geiser-impl--add-to-alist
calls (and geiser-activate-implementation calls too, which is already
inline-able) will be inlined, fixing the issue.
Fixes#4863
