Fix compiler execution time measurement

JPenuchot opened this issue · comments

Compiler execution time measurement through ttw seems to be broken, the time values it reports aren't coherent with Clang's time trace profiler. More works needs to be done to measure compiler execution more precisely, and Hyperfine seems to have that figured out so it's worth having a look and reproduce their measurement method in ttw.
