Hulk 6.6 did not use OPTIMIZE_INLINING. It used the gnu_inline
attribute, which caused the inline functions to not be actually
inlined, introducing performance issues. Therefore, we set it to
be editable (disabled by default) and made adjustments to some
functions that had linking conflicts.

  Revert "compiler: remove CONFIG_OPTIMIZE_INLINING entirely"
  make OPTIMIZE_INLINING config editable
