[lldb] Fix bug to update process public run lock with process state
This patch should address an issue that caused the process public run
lock to not be updated during a process launch/attach when the process
stops.
That caused the public run lock to report its state as running while the
process state is stopped. This prevents the users to interact with the
process (through the command line or via the SBAPI) since it's
considered still running.
To address that, this patch refactors the name of the internal hijack
listeners to a specific pattern `lldb.internal.<action>.hijack` that
are used to ensure that we've attached to or launched a process successfully.
Then, when updating the process public state, after updating the state
value, if the process is not hijacked externally, meaning if the process
doens't have a hijack listener that matches the internal hijack
listeners pattern, we can update the public run lock accordingly.

[mlir][openacc] Refine data operation data clause attribute
The data operations added in D148389 hold two data clause fields:
"dataClause" and "decomposedFrom". However, in most cases, dataClause
field holds a default value (except for acc_copyin_readonly,
acc_create_zero, and acc_copyout_zero).
The decomposedFrom field holds the original clause specified by user.
As work began on lowering to these new operations [1], it seems that
having both fields adds a bit of ambiguity. There is only one scenario
where we actually intended to use both:
acc data copyout(zero:)
The original intent was that this clause would be decomposed to
the following operations:
acc.create {dataClause = acc_create_zero, decomposedFrom =
acc_copyout_zero}
...
acc.copyout {dataClause = acc_copyout_zero}
However, we can encode the zero semantics like so without need of both:
acc.create {dataClause = acc_copyout_zero}
...
acc.copyout {dataClause = acc_copyout_zero}
Thus get rid of the decomposedFrom field and update verifier checks
to check for all data clauses that can be decomposed to the particular
operation.
So now the dataClause holds the original user's clause which simplifies
understanding of the operation.

[compiler-rt] [test] [profile] Avoid issues with an implicit .exe suffix
Mingw toolchains implicitly add an .exe suffix if the output linked

cause any issues, but in some tests, this discrepancy between expected
output file name and actual output file does affect the tests.
In one test, a rm command fails to remove the executable since it
doesn't have the expected name. By failing to remove the executable, the
later llvm-profdata command tries to read the executable as if it was
a profile data file.
In another test, when the Python executor executes commands, it can
resolve executable names without the extra .exe suffix for absolute
paths (when most binaries are executed as e.g. "%t/foo"), but it fails
to resolve the executables for relative paths such as "./foo". Making
the paths absolute by using %t here shouldn't affect what the test tries
to validate.

[libc++] Remove symbols for a std::allocator_arg & friends from the dylib
This patch removes the symbols defined in the library for std::allocator_arg,
std::defer_lock, std::try_to_lock, std::adopt_lock, and std::piecewise_construct.
Those were defined in the library because we provided them in C++03 as an
extension, and in C++03 it was impossible to define them as `constexpr`
variables, like in the spec.
This is technically an ABI break since we are removing symbols from the
library. However, in practice, only programs compiled in C++03 mode who
take the address of those objects (or pass them as a reference) will have
an undefined ref to those symbols. In practice, this is expected to be
rare. First, those are C++11 features that we happen to provide in C++03,
and only the C++03 definition can potentially lead to code referencing
the dylib definition. So any code that is using these objects but compiling
in C++11 mode (as they should) is not at risk. Second, all uses of these
types in the library is done by passing those types by value to a function
that can get inlined. Since they are empty types, the compiler won't
generate an undefined reference if passed by value, since there's nothing
to pass anyway.
Long story short, the risk for code actually containing an undefined
reference to one of these types is rather small (but non-zero). I also
couldn't find any app on the App Store that referenced these symbols,
which supports my impression that this won't be an issue in practice.

[lldb] Fix bug to update process public run lock with process state
This patch should address an issue that caused the process public run
lock to not be updated during a process launch/attach when the process
stops.
That caused the public run lock to report its state as running while the
process state is stopped. This prevents the users to interact with the
process (through the command line or via the SBAPI) since it's
considered still running.
To address that, this patch refactors the name of the internal hijack
listeners to a specific pattern `lldb.internal.<action>.hijack` that
are used to ensure that we've attached to or launched a process successfully.
Then, when updating the process public state, after updating the state
value, if the process is not hijacked externally, meaning if the process
doens't have a hijack listener that matches the internal hijack
listeners pattern, we can update the public run lock accordingly.
