AMDGPU: Directly implement computeKnownBits for workitem intrinsics
Currently metadata is inserted in a late pass which is lowered
to an AssertZext. The metadata would be more useful if it was
inserted earlier after inlining, but before codegen.
Probably shouldn't change anything now. Just replacing the
late metadata annotation needs more work, since we lose
out on optimizations after these are lowered to CopyFromReg.
Seems to be slightly better than relying on the AssertZext from the
metadata. The test change in cvt_f32_ubyte.ll is a quirk from it using

GlobalISel: Relax handling of G_ASSERT_* with source register classes
The most common situation where G_ASSERT_ZEXT appears for AMDGPU is a
copy from a physical register, which happens to use set the actual
register class on the virtual register. After copy coalescing, the
assert's source operand had a vreg with a set class. The verifier was
strictly rejecting cases where the set class/bank weren't an exact
match. Additionally, RegBankSelect was also expecting a register bank
to be set on the register, not a class.
This is much stricter than regular copies so relax this behavior. This
now allows these 2 cases:
1. Source register has either class or bank, and the result does not
2. Source register has a register class, and the result is a register
with a matching bank.
This should avoid needing some kind of special handling to avoid
violating this constraint when folding copies.

[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.

[mlgo][nfc] Decouple TensorSpec from tensorflow.
The motivation is twofold:
1) Allow plugging in a different training-time evaluator, e.g.
TFLite-based, etc.
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.

D70524 added support for auto return types for C++ member functions. I was

how gcc was handling these cases and it appears gcc emits the deduced return type for lambdas.

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.
