llvm dev - Oct 2019 - Deleting BasicBlockPass/Manager

Hi,

I sent out a patch (D69121 <https://reviews.llvm.org/D69121>)  removing
the
BasicBlockPass, BasicBlockManager and all their dependencies following the
patch that cleaned up the instantiations of the BasicBlockPass (rL373254
<https://reviews.llvm.org/rL373254>).

The motivation was that the BasicBlockManager was generally unused,
untested, was potentially broken (PR42264
<https://bugs.llvm.org/show_bug.cgi?id=42264>, PR43429
<https://bugs.llvm.org/show_bug.cgi?id=43429>, PR43336
<https://bugs.llvm.org/show_bug.cgi?id=43336>, PR42246
<https://bugs.llvm.org/show_bug.cgi?id=42246>), and any BasicBlockPass
could be updated to be a FunctionPass looping over all BBs.

If you have comments or concerns about this cleanup please let me know.

Best,
Alina
