AMDGPU: Handle more TargetParser queries in tablegen
Previously we had various enum switches. Start generated tables
indexed by enums. Avoid some special cases by defining the dummy
"generic" and "generic-hsa" targets as real processors.

AMDGPU: Generate TargetParser table from TableGen
Migrate .def file to tablegen. The initial TargetParser
AMDGPU backend only handled R600. Extend to modern targets.
Stub out some tablegen definitions which will be used in future
changes.

[RISCV] Add macro fusion support for the Xqci extension instructions (#209542)
Add macro fusion definitions for the Qualcomm Xqci extension covering
movimm-alu, movimm-mul, movimm-ldst, movimm-jump, movimm-longlogical,
movimm-mov, mov-mov, mov-longlogical fusions.
The fusion definitions live in a new RISCVMacroFusionXQCI.td which is
included from RISCVMacroFusion.td. A MIR test and the feature list test
are updated accordingly.
To accomodate additional features, increased MAX_SUBTARGET_FEATURES to
448 (from 384).

[libc] Implement cpp::unique_ptr utility (#206701)
[libc] Implement cpp::unique_ptr utility
Implemented cpp::unique_ptr and cpp::default_delete in
libc/src/__support/CPP/unique_ptr.h for internal use within LLVM-libc.
* Added cpp::default_delete and its array specialization.
* Implemented cpp::unique_ptr with support for custom deleters and
array specialization.
* Applied LIBC_TRIVIAL_ABI to unique_ptr and LIBC_NO_UNIQUE_ADDRESS to
the
deleter to enable empty member optimization and register-passing ABI.
* Defined portable LIBC_NO_UNIQUE_ADDRESS and LIBC_TRIVIAL_ABI macros in
attributes.h.
* Included is_assignable.h in type_traits.h to support conversion
assignment constraints.
* Modernized template constraints using enable_if_t and
is_convertible_v.

[libc++] Require selecting a machine when dispatching the benchmark workflow (#212591)
This resolves a TODO to allow selecting which machine we're running on.
As I am working on automation to dispatch these benchmarking jobs, it
turns out that we always want to specify the machine, and we always want
to specify a single machine to run per workflow, since this is the only
way we can track which commits have been attempted (or are still in
flight) on a given machine.
Therefore, the ability to run benchmarks on all machines at once is
removed from this workflow (but not from the related PR A/B benchmarking
workflow).
This patch also includes the machine name and the commit being
benchmarked into the runs's name, which is necessary for automation to
know what the workflow was benchmarking.
[RISC-V] Do not emit cm.popret[z] with zicfiss (#196267)
When emitting shadow call stack protection instructions, the push/pop
optimization needs to be turned off because an sspopchk before a
cm.popret[z] is guaranteed to fail in a non-leaf function. In addition,
the sspopchk must be emitted after a cm.pop so that the ra has the
correct value when the check is performed.

AMDGPU: Remove some assembler tests using dummy target
In the future it will be illegal to do anything with a binary
without a specific subarch. Most of these were redundant with an
existing run line.
kern_pdwait(): print the process pointer through pd
to avoid using uninitialized value in the KASSERT() statement on the first
iteration.
Also, do the assert under the proctree_lock, which is not critical but
satisfies the invariants.

[clang-format] Fix OverEmptyLines aligning trailing comments across block boundaries (#208324)
Fix `AlignTrailingComments` with `OverEmptyLines` aligning trailing
comments across block boundaries (e.g., between two functions or

(`BK_Block`).
This is an `OverEmptyLines` bug exposed by

Triple: Add query for the default long double format (#211239)
The long double format changes the library call info, which needs

pmc: enable the new pmc commands
This change hooks everything up to the pmc command and improves the
usage to document all functions. There are a couple older commands that
are currently broken that I have hidden from the usage, but left in the
code for those using it. I won't remove those until we have our
replacements upstreamed that depend on the AMD PMC multiplexing patches.

pmc: pmc frontend stall analysis based on IBS
The frontend command uses AMD IBS frontend events to analyze the major
sources of frontend stalls. It displays a table breakind down the major
causes of front end stalls. This is a simple demonstration of the tools
as you can use the filtering tools to limit the analysis to a subset of
the samples including filtering by fetch latencies.

pmc: pmc record command
The record command is designed around the idea of predefined studies.
While you can still select individual counters, the predefined studies

It implements all of the base studies that I have built so far.
