Andreas Kling dea474dfd5 Make loading /bin/bash ~250x faster. ...

The ELF loader was doing huge amounts of unnecessary work.
Got rid of the "export symbols" and relocation passes since we don't need them.
They were useful things when bringing up the ELF loading code.

Also added a simple TSC-based Stopwatch RAII thingy to help debug performance issues.
