jump label/x86/sparc64: Remove !CC_OPTIMIZE_FOR_SIZE config conditions

The !CC_OPTIMIZE_FOR_SIZE was added to enable the jump label functionality
because Jason noticed that the gcc option would not optimize the labels
and may even hurt performance.

But this is a gcc problem not a kernel one. Removing this condition should
add motivation to the gcc developers to actually fix it.
