Reapply "[InstCombine] Always fold alignment assumptions into operand bundles (#177597)" (#179497)
Truncating at 32 bits is now avoided by removing a cast to `unsigned`.
This would also break at 64 bits (with the pointer size > 64 bit), but I
don't think LLVM supports such a
thing.
This reverts commit bc7315749d6d16d0f162f816b3ec0ef7169615f2.
ARM: Avoid using isTarget wrappers around Triple predicates (#179512)
These are module level properties, and querying them through
a function-level subtarget context is confusing. Plus we don't
need an aliased name.

[LoopUnroll] Fix block frequencies for newly unconditional latches
As another step in issue #135812, this patch fixes block frequencies
when LoopUnroll converts a conditional latch in an unrolled loop
iteration to unconditional. It thus includes complete loop unrolling
(the conditional backedge becomes an unconditional loop exit), which
might be applied to the original loop or to its remainder loop.
As explained in detail in the header comments on the
fixProbContradiction function that this patch introduces, these
conversions mean LoopUnroll has proven that the original uniform latch
probability is incorrect for the original loop iterations associated
with the converted latches. However, LoopUnroll often is able to
perform these corrections for only some iterations, leaving other
iterations with the original latch probability, and thus corrupting
the aggregate effect on the total frequency of the original loop body.
This patch ensures that the total frequency of the original loop body,
summed across all its occurrences in the unrolled loop after the

Implement `ByteAddressBuffer` Load/Store methods (#176058)
Closes #108058.
This PR:
- Adds the `uint` `Load` and `Store` methods (`Load/Store`,
`Load2/Store2`, `Load3/Store3`, `Load4/Store4`) to the existing
`ByteAddressBuffer` objects
- Adds the new templated `Load` and `Store` methods to
`ByteAddressBuffer` objects, which allow types other than `uint` (e.g.
aggregate types) to be used with them directly
- One exception to this is array types, which are rejected by the
methods (as array returns will be disallowed in 202x)
- Adds the relevant `AST`, `CodeGenHLSL`, and `SemaHLSL` tests for these
methods
*Note: the `HLSL Tests` check is failing because this implementation
makes the `ByteAddressBuffer` tests XPASS. Will remove the XFAILs from
these tests in a follow-up.*
[clang][ssaf] Add FormatInfo sub-registry and tests [3/3]
Add `FormatInfoEntry` template to support per-analysis-type serialization
within a `SerializationFormat`.
This allows to implement different formats for the different analyses in
a decoupled way.
For testing, this patch also implements the MockSerializationFormat
demonstrating the FormatInfo sub-registry pattern.

[MLIR] Enforce symbol visibility during symbol lookup (#179370)
Update symbol resolution to examine whether a nested symbol being
resolved is private, and fail in that case. This ensures that we
maintain invariants on symbol visibility that we depend on in
optimisations.
[clang][ssaf] Add SerializationFormatRegistry [2/3]
Add a registry infrastructure for SerializationFormat implementations,
enabling registration and instantiation of different serialization formats.
For example:
```c++
static SerializationFormatRegistry::Add<MyFormat>
RegisterFormat("MyFormat", "Description");
```
Formats can then be instantiated by name using `makeFormat()`.
The patch also updates the SerializationFormat base class to accept
FileSystem and OutputBackend parameters for virtualizing I/O
operations.

[llvm][Support] Add InMemoryOutputBackend [1/3]
Add InMemoryOutputBackend, an output backend that creates files in
memory backed by string buffers in a map.
This is useful for unittests, where we don't want to create files on the
file system, but still want to check the content of the created files.
