  1. [MIR] Add simple PRE pass to MachineCSE

    This is the second part of the commit fixing PR38917 (hoisting
    partitially redundant machine instruction). Most of PRE (partitial
    redundancy elimination) and CSE work is done on LLVM IR, but some of
    redundancy arises during DAG legalization. Machine CSE is not enough
    to deal with it. This simple PRE implementation works a little bit
    intricately: it passes before CSE, looking for partitial redundancy
    and transforming it to fully redundancy, anticipating that the next
    CSE step will eliminate this created redundancy. If CSE doesn't
    eliminate this, than created instruction will remain dead and eliminated
    later by Remove Dead Machine Instructions pass.

    The third part of the commit is supposed to refactor MachineCSE,
    to make it more clear and to merge MachinePRE with MachineCSE,
    so one need no rely on further Remove Dead pass to clear instrs
    not eliminated by CSE.

    First step:

  2. [CaptureTracking] Don't let comparisons against null escape inbounds pointers

    Pointers that are in-bounds (either through dereferenceable_or_null or
    thorough a getelementptr inbounds) cannot be captured with a comparison
    against null. There is no way to construct a pointer that is still in
    bounds but also NULL.

    This helps safe languages that insert null checks before load/store
    instructions. Without this patch, almost all pointers would be
    considered captured even for simple loads. With this patch, an icmp with
    null will not be seen as escaping as long as certain conditions are met.

    There was a lot of discussion about this patch. See the Phabricator
    thread for detals.
