Remove beforeExecuteLTOPasses callback
This callback had very unclear semantics and the current use was suprising.
Specifically, it took a PassManager parameter, but adding anything to this pass
manager would cause the passes to be executed after the other LTO passes The
only way to execute passes before the LTO passes, was to create a new pass
manager that executes a pass right before all LTO passes (that have already
being queued in the pass manager passed in as a parameter) will be executed.
The very same behavior can be achieved by just adding our passes to the
normal pass manager using the "BeforeAddLTOPasses" callback.
We used this callback to schedule the ForEachExpand pass. This pass is now
moved to the beforeAddLTOPasses callback.
