[MLIR][Affine] Simplify nested modulo operations when able
It is the case that, for all positive a and b such that b divides a
(e mod (a * b)) mod b = e mod b. For example, ((d0 mod 35) mod 5) can
be simplified to (d0 mod 5), but ((d0 mod 35) mod 4) cannot be simplified
further (x = 36 is a counterexample).
This change enables more complex simplifications. For example,
((d0 * 72 + d1) mod 144) mod 9 can now simplify to (d0 * 72 + d1) mod 9
and thus to d1 mod 9. Expressions with chained modulus operators are
reasonably common in tensor applications, and this change _should_

Added IsCoarray functions to determine if an expression is a coarray (corank > 1).
Added save attribute to coarray variables in test file, this_image.f90.

[X86] Refactor GetSSETypeAtOffset to fix pr51813
D105263 adds support for _Float16 type. It introduced a bug (pr51813) that generates a <4 x half> type instead the default double when passing blank structure by SSE registers.
Although I doubt it may expose a bug somewhere other than D105263, it's good to avoid return half type when no half type in arguments.

[compiler-rt][test] Ensure CMAKE_SYSROOT is added as a test cflag if provided
When running tests like SanitizerCommon-asan-x86_64-Linux :: Linux/crypt_r.cpp,
it may attempt to use the host header crypt.h rather than a sysroot header.
This is significant in the event where struct crypt_data defined on host is
different from the sysroot used to make the sanitizer runtime libraries. This
can result in logical differences between the expected size/layout of struct
crypt_data known by sanitizers and the strict crypt_data provided by the host crypt.h.
Since tests should still use the CMAKE_SYSROOT, this ensures that CMAKE_SYSROOT
is propagated to compiler-rt tests.

[ORC] Add finalization & deallocation actions, SimpleExecutorMemoryManager class
Finalization and deallocation actions are a key part of the upcoming
JITLinkMemoryManager redesign: They generalize the existing finalization and
deallocate concepts (basically "copy-and-mprotect", and "munmap") to include
support for arbitrary registration and deregistration of parts of JIT linked
code. This allows us to register and deregister eh-frames, TLV sections,
language metadata, etc. using regular memory management calls with no additional
IPC/RPC overhead, which should both improve JIT performance and simplify
interactions between ORC and the ORC runtime.
The SimpleExecutorMemoryManager class provides executor-side support for memory
management operations, including finalization and deallocation actions.
This support is being added in advance of the rest of the memory manager
redesign as it will simplify the introduction of an EPC based
RuntimeDyld::MemoryManager (since eh-frame registration/deregistration will be
expressible as actions). The new RuntimeDyld::MemoryManager will in turn allow
us to remove older remote allocators that are blocking the rest of the memory
manager changes.

[Support] Convert BinaryStream class zoo to 64-bit offsets
Most PDB fields on disk are 32-bit but describe the file in terms of MSF
blocks, which are 4 kiB by default.
So PDB files can be a bit larger than 4 GiB, and much larger if you create them
with a block size > 4 kiB.
This is a first (necessary, but by far not not sufficient) step towards
supporting such PDB files. Now we don't truncate in-memory file offsets (which
are in terms of bytes, not in terms of blocks).
No effective behavior change. lld-link will still error out if it were to
produce PDBs > 4 GiB.

[lldb] Refactor and rename CPlusPlusLanguage::FindAlternateFunctionManglings

1. Disambiguate between CPlusPlus::FindAlternateFunctionManglings and
IRExecutionUnit::FindBestAlternateMangledName. These are named very
similar things, they try to do very similar things, but their
approaches are different. This change should make it clear that one
is generating possible alternate manglings (through some
heuristics-based approach) and the other is finding alternate
manglings (through searching the SymbolFile for potential matches).
2. Change GenerateAlternateFunctionManglings from a static method in
CPlusPlusLanguage to a virtual method in Language. This will allow us
to remove a direct use of CPlusPlusLanguage in IRExecutionUnit,
further pushing it to be more general. This change doesn't meet this
goal completely but allows for it to happen later.

CPlusPlusLanguage, it does bring us closer to that goal.
