Szabolcs NagyandRich Felker 3c3763fc52 math: add macros for static branch prediction hints 
These don't have an effectw with -Os so not useful with default settings
other than documenting the expectation.

With --enable-optimize=internal,malloc,string,math the libc.so code size
increases by 18K on x86_64 and performance varies in -2% .. +10%.
