[PATCH 04/15] static_call: Use global functions for the self-test

[Sami Tolvanen]

With CONFIG_CFI_CLANG, the compiler renames static functions. This
breaks static_call users using static functions, because the current
implementation assumes functions have stable names by hardcoding them
in inline assembly. Make the self-test functions global to prevent the
compiler from renaming them.
