[mlir][IR] Add Iterator template option to IR walkers
This allows users to specify a top-down or bottom-up traversal of the IR, in addition to the already existing WalkOrder.
Certain transformations work better with a forward traversal. E.g., when cloning a piece of IR, operations should be cloned top-down so that all uses are defined when creating an op.
Certain transformations work better with a reverse traversal. E.g., when erasing a piece of IR, operations should be erased bottom-up to avoid erasing operations that still have users.

[SCEV] Ensure SCEV does not replace aliases with their aliasees
Passes in general shouldn't replace an alias with the aliasee (see
https://reviews.llvm.org/D66606). This can lead to situations where a
linkonce_odr symbol (which could be interposable if lowered to weak
linkage) can be replaced with a local aliasee which won't be
interposable. SVEC does this when the function is invoked by
FunctionPass Manager -> Loop Pass Manager -> Induction Variable Users in
the codegen pipeline. This was found in hwasan instrumented code where a
linonce_odr alias was replaced with its private aliasee.
This fixes the bug descriped at

[ASan][libcxx] Annotating std::vector with all allocators
This revision is a part of a series of patches extending
AddressSanitizer C++ container overflow detection
capabilities by adding annotations, similar to those existing
in std::vector, to std::string and std::deque collections.
These changes allow ASan to detect cases when the instrumented
program accesses memory which is internally allocated by
the collection but is still not in-use (accesses before or
after the stored elements for std::deque, or between the size and
capacity bounds for std::string).
The motivation for the research and those changes was a bug,
found by Trail of Bits, in a real code where an out-of-bounds read
could happen as two strings were compared via a std::equals function
that took iter1_begin, iter1_end, iter2_begin iterators
(with a custom comparison function).
When object iter1 was longer than iter2, read out-of-bounds on iter2
could happen. Container sanitization would detect it.
In revision D132522, support for non-aligned memory buffers (sharing
first/last granule with other objects) was added, therefore the
check for standard allocator is not necessary anymore.
This patch removes the check in std::vector annotation member
function (__annotate_contiguous_container) to support
different allocators.
Additionally, this revision fixes unpoisoning in std::vector.
It guarantees that __alloc_traits::deallocate may access returned memory.

Avoid strict aliasing violation on type punning inside llvm::PointerIntPair

`getAddrOfPointer()` casts the underlying storage as if it was a
`PointerTy`
This violates strict aliasing, so depending on how they are used, it's
possible to have the compiler to optimize the code in unwanted ways.
See the unit test in the patch. We declare a `PointerIntPair` and use
the `getAddrOfPointer` method to fill in the a pointer value. Then,
