Revert "Run Coverage pass before other *San passes under new pass manager"

This reverts commit 7d5bb94d.

Reverting since this leads to a linker error we're seeing on Fuchsia.
The underlying issue seems to be that inlining is run after sanitizers
and causes different comdat groups instrumented by Sancov to reference
non-key symbols defined in other comdat groups.

Will re-land this patch after a fix for that is landed.
