Hello,
   thank you for the hotfix that repaired switch/case missing return value.

Actually I was told by Jan to reproduce the functionality from varasm.c that I
was able to bootstrap and test.

The idea of reordering pass is to order all functions that are seen during
instrumentation run and are executed during start-up of an application.

So that, we do not build separate sections for .text, .text.hot and
.text.startup. On the other hand: any execute function should not live in
.text.unlikely and .text.startup. If so, it means that we miss profile info and
these functions can be identified during debugging process.

I am not familiar with darwin format, Jan do you know what could cause problem?
