New BLI_NOINLINE macro

This macro is handy in at least two occasions:
* When you want to check the optimized generated assembly for
some small function that would get inlined otherwise.
* The marked function will be visible in profiling results.

I can't test the implementations for other compilers now,
so I did not include them.
