[PATCH liburing v1 1/2] lib: Add __hot and __cold macros

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

A prep patch. These macros will be used to annotate hot and cold
functions. Currently, the __hot macro is not used, we will only use
the __cold macro at the moment.
