[InstCombine] remove fold that swaps xor/or with constants; NFCI
// (X ^ C1) | C2 --> (X | C2) ^ (C1&~C2)
This canonicalization was added at:
https://reviews.llvm.org/rL7264
By moving xors out/down, we can more easily combine constants. I'm adding
tests that do not change with this patch, so we can verify that those kinds
of transforms are still happening.
This is no-functional-change-intended because there's a later fold:
// (X^C)|Y -> (X|Y)^C iff Y&C == 0
...and demanded-bits appears to guarantee that any fold that would have
hit the fold we're removing here would be caught by that 2nd fold.
Similar reasoning was used in:

the fix for PR32706:

[libc++] Refactor Windows support headers.
Summary:
This patch refactors and tries to remove as much of the Windows support headers as possible. This is needed because they currently introduce super weird include cycles and dependencies between STL and libc headers.
The changes in this patch are:
* remove `support/win32/support.h` completely. The required parts have either been moved into `support/win32/msvc_support.h` (for `MSVC` only helpers not needed by Clang), or directly into their respective `foo.h` headers.
* Combine `locale_win32.h` and `locale_mgmt_win32.h` into a single headers, this header should only be included within `__locale` or `locale` to avoid include cycles.
* Remove the unneeded parts of `limits_win32.h` and re-name it to `limits_msvc_win32.h` since it's only needed by Clang.
I've tested this patch using Clang on Windows, but I suspect it might technically regress our non-existent support for MSVC. Is somebody able to double check?
This refactor is needed to support upcoming fixes to `<locale>` on Windows.

[DeLICM] Always normalize domain. NFC.

argument object after the call uses different contraints to represent
the same set. Different contraints can result in different outputs

In assert builds additional isl functions are called (in assert() or
mentioned, these can change the internal representation of its read-only
arguments such that printed strings are different in debug and non-debug
builds.
What happened here is that a call to isl_set_is_equal inside an assert
in getScatterFor normalizes one of its arguments such that one redundant
constraint is removed. The redundant constraint therefore does not appear
in the string representing the domain, which FileCheck notices as a
regression test failure compared to a build with assertions disabled.
This fix removes the redundant contraints the domain from the start such
that the redundant contraint is removed in assert and non-assert builds.
Isl adds a flag to such sets such that the removal of redundancies is
not done multiple times (here: by isl_set_is_equal).

> In the constructor definitions below, enables shared_from_this with p, for a pointer p of type Y*, means

This means that libc++ needs to respect the access specifier of the base class, and not attempt to construct
and enabled_shared_from_this base if it is private. However access specifiers don't affect overload resolution
so our current implementation will attempt to construct the private base.
This patch uses SFINAE to correctly detect if the shared_ptr input has an accessible enable_shared_from_this
base class.

Add dyld to sanitizer procmaps on darwin
Summary:
Sanitizer procmaps uses dyld apis to iterate over the list of images
in the process. This is much more performan than manually recursing
over all of the memory regions in the process, however, dyld does
not report itself in the list of images. In order to prevent reporting
leaks from dyld globals and to symbolize dyld functions in stack traces,
this patch special-cases dyld and ensures that it is added to the
list of modules.
This is accomplished by recursing through the memory map of the process
until a dyld Mach header is found. While this recursion is expensive,
it is run before the full set of images has been loaded in the process,
so only a few calls are required. The result is cached so that it never
needs to be searched for when the full process memory map exists, as this
would be incredibly slow, on the order of minutes for leak sanitizer with
only 25 or so libraries loaded.

[ELF] - Don't segfault when assigning non-calculatable absolute symbol value.
This is PR32664.
Issue was revealed by linux kernel script which was:
SECTIONS {
. = (0xffffffff80000000 + ALIGN(0x1000000, 0x200000));
phys_startup_64 = ABSOLUTE(startup_64 - 0xffffffff80000000);

At the place of assignment to phys_startup_64 we can not calculate absolute value for startup_64
because .text section has no VA assigned. Two patches were prepared earlier to address this: D32173 and D32174.
And in comments for D32173 was suggested not try to support this case, but error out.
