In the original code, the 'getDeclAlignIfRequired' function is used.
The 'getDeclAlignIfRequired' function will return the max alignment
of all aligned attributes if the type has aligned attributes. The
function doesn't consider the type at all.
The 'getTypeAlignIfRequired' function uses the type's alignment value,

[flang] Make the plugin API independent of the driver internals
This patch adds a few new member methods in the `PluginParseTreeAction`
frontend action base class. With these new methods, the plugin API
becomes independent of the driver internals. In particular, plugin
writers no longer require the `CompilerInstance.h` header file to access
various driver data structures (instead, they can use newly added
hooks).
This change is desirable as `CompilerInstance.h` includes various
headers from Clang (both explicitly and implicitly). Some of these
header files are generated at build time (through TableGen) and
including them creates a dependency on some of Clang's build targets.
However, plugins in Flang should not depend on Clang build targets.
Note that plugins might still work fine most of the time, even without
this change and without adding Clang build targets as dependency in
plugin's CMake definition. Indeed, these Clang build targets are often
generated early in the build process. However, that's not guaranteed and
we did notice that on occasions plugins would fail to build.

These types may be specified with -xc++-{user,system,header-unit}-header xxxx.
These types allow us to disambiguate header unit jobs from PCH ones, and thus

PCH file, as would be the case for other headers).
2. When the type is "user" or "system" we defer checking for the file until the

The motivation is twofold:

2) Allow using TensorSpec for AOT, too, to support evolution: we start
by extracting a superset of the features currently supported by a
model. For the tensors the model does not support, we just return a
valid, but useless, buffer. This makes using a 'smaller' model (less
supported tensors) transparent to the compiler. The key is to
dimension the buffer appropriately, and we already have TensorSpec
modeling that info.
The only coupling was due to the reliance of a TF internal API for
getting the element size, but for the types we are interested in,
`sizeof` is sufficient.
A subsequent change will yank out TensorSpec in its own module.

Fix sanitizer stack traces on aarch64.
Fixes llvm-project/compiler-rt/test/asan/TestCases/null_deref.cpp on
macOS/aarch64.
The bp (base pointer) variable was being loaded from register LR and
not FP on aarch64 (except for this narrow case):
defined(__IPHONE_8_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0
Without a valid bp from the FP register, it is not possible to traverse
previous frames for a complete stack trace. The rationale for fetching
the LR as the bp for all cases except above is not clear but since the
FP register is the canonical register for use as the frame pointer, this
commit removes the restriction above for unconditional use all aarch64.

[Testing] TestAST, a helper for writing straight-line AST tests
Tests that need ASTs have to deal with the awkward control flow of
FrontendAction in some way. There are a few idioms used:
- don't bother with unit tests, use clang -dump-ast
- create an ASTConsumer by hand, which is bulky
- use ASTMatchFinder - works pretty well if matchers are actually
needed, very strange if they are not
- use ASTUnit - this yields nice straight-line code, but ASTUnit is a
terrifically complicated library not designed for this purpose
TestAST provides a very simple way to write straight-line tests: specify
the code/flags and it provides an AST that is kept alive until the
object is destroyed.
It's loosely modeled after TestTU in clangd, which we've successfully
used for a variety of tests.
I've updated a couple of clang tests to use this helper, IMO they're clearer.

[AsmParser/Printer] Rework sourceloc support for function arguments.
When Location tracking support for block arguments was added, we
discussed various approaches to threading support for this through
function-like argument parsing. At the time, we added a parallel array
of locations that could hold this. It turns out that that approach was
verbose and error prone, roughly no one adopted it.
This patch takes a different approach, adding an optional source
locator to the UnresolvedOperand class. This fits much more naturally
into the standard structure we use for representing locators, and gives
all the function like dialects locator support for free (e.g. see the
test adding an example for the LLVM dialect).
