[clang][bytecode] Fix an assertion failure in dynamic_cast handling (#206447)
If `Ptr` is already a root pointer, the `getBase()` call ran into an
assertion. Fix this by moving the check to the start of the loop.
[AMDGPU] Fix bit-packing condition in LiveRegOptimizer (#201520)
This commit changes the condition for determining the eligibility for
bit-packing in LiveRegOptimizer from requiring that the scalar target
type is larger than the source type to instead require that the target
is a multiple of it.
Fixes https://github.com/llvm/llvm-project/issues/196582.

[RFC][SIInsertWaitCnts] Remove VMemTypes
This can be considered a RFC. I'd personally like to get rid of VMEMTypes
but I don't know if anyone feels strongly that they should be kept.
My motivation for removing VMemTypes is simple: They are just a repeat
of VMEM events, just under a different name, and messier (defined as a
basic enum but actually stored as a bitmask later). It's just confusing.
This patch eliminates the need for them by:
- Adding a new entrypoint in AMDGPUHWEvents to get the basic set of
VMEM events issued by a VMEM Instruction.
- Set BVH/SAMPLER events irrespective of whether the HW can track them.
These events exist anyway, it should be up to InsertWaitCnt to deal with them
properly (which is easy, only `counterOutOfOrder` needed work).
- Tracking an additional set of per-VGPR "PendingEvents" which is
set using the "basic set of VMEM events" and cleared as needed.

[AMDGPU][InsertWaitCnts] Improve testing coverage for VMemTypes (#206439)
The next patch will get rid of VMEMTypes, but some of its functionality
was not tested well. This patch adds more tests to fix gaps in testing
so that the next patch in the stack can be shown to have no impact
on codegen.
The 2 issues I had noticed was that we didn't have a test for mixed
vmem types w/ BVH, only for sampler; we also did not have a test
that was affected by `clearVmemTypes`, so removing that call
had no effect.
This patch adds tests for both cases.
Handle TNC license delivery and token states in heartbeat
This commit adds changes to read the TNC heartbeat response body so we can report the system fingerprint and installed license id, install a license PEM that TNC delivers, and drive token rotation and the terminal token states off the body fields instead of the old X-New-Token header. A delivered license is deduped against the one already installed so we don't reinstall it every beat, and a 205 that carries no license or token is logged as a TNC fault rather than silently skipped.
[Dexter] Switch to using script-mode by default
This patch changes the default mode of Dexter from heuristic-mode to
script-mode. The --use-script argument is replaced with --use-heuristic,
some comments/docs/error messages are updated accordingly, and tests have
their flags switched accordingly.
[Dexter] Update lldb-based dexter-tests to use script-mode
This patch replaces uses of heuristic-mode Dexter in the dexter-tests suite
with uses of the script-mode, for tests that use DAP (via lldb-dap). The
updates are largely straightforward but occasionally non-trivial, and in
some cases some slight modifications have been made to keep the "spirit" of
the test intact.
[Dexter] Document the structured script model
This patch adds documentation for the script model to the Dexter README,
shunting heuristic-mode information into a separate doc, creating a new
doc for script-mode, and linking to both (with a brief summary of the
differences) from the base README.
[Dexter] Add ability to check float values within a range
Adds a new node type, !float, which can be used to match debugger ouptut as
float values rather than as strings, optionally allowing a range to be
specified for inexact matches. This new node allows a list of values to be
given, effectively a shorthand for a list of individual !float nodes.
[Dexter] Allow matching lists of values for aggregate members
This patch slightly extends the matching of aggregate members to allow for
lists of expected values for individual members, functioning the same as
lists of expected values for scalar values.
