[ARM][AArch64] Replace ".f16(bfloat" with ".bf16(bfloat" in intrinsics. NFC
It looks like these were copied from fp16 tests, and forgot to update the
intrinsic types. Also remove some old definitions that are no longer required.
Revert "[X86][APX] Add pattern for zext(X86setcc ..) -> SETZUCCr (#170806)" (#172192)
This reverts commit 2612dc9b5faeaeb180c5a5e0c282642faef8891b but keeps
`Predicates = [HasNDD]` removed.
There are two issues identified related to the change. One is
INSERT_SUBREG cannot guarantee source and dest to be the same register.
It mostly happens on O0. The other one is zero_extend is not a chain
node, as a result, we will lose the chain for SETZUCCr.
[MLIR][Python][Transform] Print diagnostics also upon success (#172188)
If we do not collect the diagnostics from the
CollectDiagnosticsToStringScope, even when the named_sequence applied
successfully, the Scope object's destructor will assert (with a
unhelpful message).
[clang-tidy][NFC] Remove obsolete FIXME comment (#172120)
This comment was written 12 years ago. It's no longer correct to say
that diagnostic reporting is under heavy development, and we seem to be
doing just fine without tablegenned IDs, so I think we can simply remove
it.
[clang][PAC] add support for options parameter to __ptrauth
This PR adds support for an 'options' parameter for the __ptrauth
qualifier.
The initial version only exposes the authehntication modes:
* "strip"
* "sign-and-strip"
* "sign-and-auth"
We also support parsing the options but not yet the implementation
* "isa-pointer"
* "authenticates-null-values"
The initial support for authentication mode controls exist to support
ABI changes over time, and as a byproduct support basic initial tests
for option parsing.
[LV] Add test coverage for remark for unprofitable RT checks.
Add test coverage for remark when runtime checks are not profitable with
threshold provided.
Also make sure that X86 remark tests actually passes an X86 triple,
which is needed for the threshold remark.
Also clean up the tests a bit.
[SelectionDAG] Support integer types with multiple registers in ComputePHILiveOutRegInfo. (#172081)
PHIs that are larger than a legal integer type are split into multiple
virtual registers that are numbered sequentially. We can propagate the
known bits for each of these registers individually.
Big endian is not supported yet because the register order needs to be
reversed.
Fixes #171671
[lldb] Add unit tests for NonNullSharedPtr (#172173)
I was investigating a crash yesterday that implicated NonNullSharedPtr
which made me realize I didn't add unit tests for my new class.
[-Wunsafe-buffer-usage] Check isValueDependent before EvaluateAsBooleanCondition (#172091)
The function `EvaluateAsBooleanCondition` assumes (asserts) that the
input `Expr` is not in a dependent context. So it is caller's
responsibility to check the condition before the call. This commit fixes
the issue in `UnsafeBufferUsage.cpp`.
The issue was first found downstream because of some code not
upstreamed. This commit also includes those un-upstreamed code.

[Clang] [NFC] Add an accessor for `ASTUnit::CodeGenOpts` (#172164)
There is currently no way to actually access `ASTUnit::CodeGenOpts`;
this is almost certainly an oversight, so this adds a getter for it.
[ADT] Only call reserve on empty containers in append_values (#172109)
Calling reserve in a loop can prevent amortized constant time appends
when the container doesn't round up the capacity.
