Duncan P. N. Exon Smith 8e3669586b verify-uselistorder: Call verifyModule() and improve output 
Call `verifyModule()` after parsing and after every transformation.
Also convert some `DEBUG(dbgs())` to `errs()` to increase visibility
into what's going on.

Duncan P. N. Exon Smith a5a8d3f6f2 verify-uselistorder: Reverse use-lists at every verification 
Updated `verify-uselistorder` to more than double the number of use-list
orders it checks.

  - Every time it verifies an order, it then reverses the order and
    verifies again.

  - It now verifies the initial order, before running any shuffles.

Changed the default to `-num-shuffles=1`, since this is already four
checks, and after r214584 shuffling is guaranteed to make a new order.

This is part of PR5680.

Duncan P. N. Exon Smith 3da117d272 verify-uselistorder: Move shuffleUseLists() out of lib/IR 
`shuffleUseLists()` is only used in `verify-uselistorder`, so move it
there to avoid bloating other executables.  As a drive-by, update some
of the header docs.

This is part of PR5680.

Rafael Espindola 3f6481d0d3 Remove some calls to std::move. 
Instead of moving out the data in a ErrorOr<std::unique_ptr<Foo>>, get
a reference to it.

Thanks to David Blaikie for the suggestion.

Duncan P. N. Exon Smith 852e00e3d1 verify-uselistorder: Change the default -num-shuffles=5 
Change the default for `-num-shuffles` to 5 and better document the
algorithm in the header docs of `verify-uselistorder`.
