[SPARC] Accept rN register names in getRegisterByName (#237528)
Accept r0-r31 as names for the integer registers in llvm.read_register
and llvm.write_register, matching the %rN syntax of the assembler.
This completes #212838, which was reverted because reading %r31/%i7 in
a leaf procedure produced a use of an undefined physical register once
leaf remapping turned it into %o7. That is fixed by #236654, which adds
live-ins for reserved registers remapped in leaf procedures. The %
prefix
and the sp/fp aliases from #212838 have since been added by #234875.
Also run the test with -verify-machineinstrs, which catches that failure
without an expensive checks build.

www/nginx-module-passenger: Add CPE information
Passenger is listed in the NVD as phusion:passenger with 456 dictionary
entries. The port name does not match the upstream product name, so
both CPE_VENDOR and CPE_PRODUCT need to be set explicitly.

net-mgmt/semaphore: Add CPE information
The NVD lists this software as ansible-semaphore:ansible_semaphore with
136 dictionary entries, so the port can be matched against advisories
once they appear. The cpe.mk defaults would have produced
semaphore:semaphore, which does not exist.

[SelectionDAG] Don't crash after an error in a callbr's asm
When a callbr's asm has an error, such as a constraint it can't satisfy,
visitInlineAsm() reports it and returns before creating the INLINEASM_BR.
But the callbr's block still got edges to the indirect targets, which
BranchFolding rejects since nothing branches there, and a landing pad in
an indirect target looked for the registers that the INLINEASM_BR would
have defined.
Don't add the edges to the indirect targets, and make a landing pad's
value poison, since nothing reaches it.
Fixes #98379 and #172657. Part of #173609, whose asm is still rejected,
since LLVM picks the "k" alternative of "+kr", which needs AVX-512.

[SelectionDAG] Report an error for a callbr's indirect register output
An indirect output with a register constraint, e.g. "=*r", is stored to its
pointer after the asm. But a callbr's asm can branch to an indirect target
before then, so the store was silently skipped on the indirect paths. Clang
emits such an output for a _Complex lvalue with a register constraint:
_Complex float c;
asm goto("" : "=r"(c) : : : l);
Report an error instead. A callbr without indirect targets has no such
path, so it's still allowed.

Replay each output's read in the indirect targets
The indirect targets re-parsed the constraints, recomputed each output's
registers and types, and paired them with the recorded registers in order,
so they were right only if both computations agreed. Record each output's
operand info and registers when lowering the callbr instead, and read them
in the indirect targets with the same code as visitInlineAsm().
This also marks a flag output's register (NZCV on AArch64, CC on SystemZ)
live into the indirect targets, as a register output's already was. And the
indirect targets no longer create virtual registers they don't use, which
renumbers some in the AArch64 test.

Move the asm error handling to its own PR
This PR now fixes only valid asm whose outputs crash the indirect targets.
Lowering a callbr whose asm has an error, which crashes after reporting
it, moves to its own PR stacked on this one.

[SelectionDAG] Read callbr outputs from the INLINEASM_BR's registers
An indirect target of a callbr found the registers holding the asm's
outputs by walking back from the callbr's exported value through COPYs to
the INLINEASM_BR, and asserted that the chain held nothing else ("start of
copy chain MUST be COPY"). An output whose type differs from its register's,
such as a float in a general-purpose register, is converted, e.g. with
MOVDI2SSrr on x86, so the assertion fired. And the target didn't convert the
output to its result type, as visitInlineAsm() does.
After an error in the asm, nothing defines the exported value, so the walk
crashed, and the callbr block kept edges to the indirect targets with no
INLINEASM_BR to branch there, which later passes reject.
Record the registers that the INLINEASM_BR defines its outputs in when
lowering the callbr, and read the outputs from them in the indirect target,
converting each to its result type as visitInlineAsm() does. After an error,
give the indirect targets undefined outputs and no edges from the callbr.
Fixes #98379, #112914, #143795, #170100, #172657, and #173609.
Remove the stale FollowCopyChain comment and unrelated comment changes
The comment that explained FollowCopyChain's walk was left above
visitCallBrLandingPad() when the walk was removed. Also put the BTI comment
in visitCallBr() back as it was, and fix a double space.

Test more outputs that the indirect targets convert
Add the RISC-V shape of #143795, where an i32 output is sign-extended on
each path, a float in a specific physical register on x86, a double in a
pair of registers on i686, and a flag output on AArch64, whose NZCV is now
live into the indirect target. Also check that a callbr with direct and
indirect register outputs now only reports the error.

[MachineCSE] Don't reuse an instruction after an INLINEASM_BR elsewhere
An INLINEASM_BR can branch to its indirect targets before the instructions
after it in its block run, but MachineCSE let those instructions replace
ones in any block that their block dominates, including the indirect
targets. E.g., when both paths out of a callbr sign-extend its output, the
indirect target reused the extension on the path to the default target and
read a register that its own path never wrote.
Reuse an instruction after an INLINEASM_BR only in its own block. MachineSink
already refuses to sink into an indirect target for the same reason.

[InlineAsmPrepare] Rewrite callbr result uses that indirect dests reach
updateSSA() left a use of a callbr's result alone if the callbr's default
dest dominated it. But an indirect dest can reach the default dest too,
e.g. when they're the same block or when the indirect dest branches to it,
so such a use still read the callbr's result on the indirect path.
SelectionDAG copies that result to a virtual register after the
INLINEASM_BR, on the path to the default dest only, so the indirect path
read a register that it never defined.
Leave a use alone only if the edge to the default dest dominates it, and
don't make the result the value at the end of the default dest, so that
SSAUpdater merges it with the landing pad's value there.

[SelectionDAG] Use the Func kind for inline asm operands only on x86 (#237504)
The only platform that currently uses the "Func" kind is x86. The other
targets aren't able to handle it. For instance, SystemZ asserts "This is
not a register operand!" and Hexagon hits an llvm_unreachable.
Gate the use of the Func kind behind a new hook
TargetLowering::supportsInlineAsmFuncOperands(), which only x86
overrides.

[UpdateTestChecks] Fix Windows error when piping outputs (#237636)
On Windows, `update_cc_test_checks` fails to update tests that pipe

after initially writing to it and then manually removing it.
