D65628 requires a flag to specify the number of threads for a clang-doc step. It would be good to use ExecutorConcurrency after exposing it instead of creating a new one that has the same purpose.

The matchSelectPattern code can match patterns like (x >= 0) ? x : -x
for absolute value. But it can also match ((x-y) >= 0) ? (x-y) : (y-x).
If the latter form was matched we can only use the nsw flag if its
set on both subtracts.
This match makes sure we're looking at the former case only.

Summary:
This patch adds support for using unified memory in the case of regular maps that happen when a target region is offloaded to the device.
For cases where only a single version of the data is required then the host address can be used. When variables need to be privatized in any way or globalized, then the copy to the device is still required for correctness.

Some of these names were abbreviated, some were not, some pluralised,
some not. Made the API difficult to use - since it's an exact 1:1

We built a StringRef from a string literal which we then converted to a
std::string to call c_str(). Just use a pointer to the string literal
instead of a StringRef.

The assert that caused this to be reverted should be fixed now.
Original commit message:
This patch changes our defualt legalization behavior for 16, 32, and
64 bit vectors with i8/i16/i32/i64 scalar types from promotion to
widening. For example, v8i8 will now be widened to v16i8 instead of
promoted to v8i16. This keeps the elements widths the same and pads
with undef elements. We believe this is a better legalization strategy.
But it carries some issues due to the fragmented vector ISA. For
example, i8 shifts and multiplies get widened and then later have
to be promoted/split into vXi16 vectors.
This has the potential to cause regressions so we wanted to get
it in early in the 10.0 cycle so we have plenty of time to
address them.
Next steps will be to merge tests that explicitly test the command
line option. And then we can remove the option and its associated
code.

Resolve the path in the target create output. This is nice when passing
relative paths to the lldb command line driver.
$ lldb ./binary
(lldb) target create "./binary"
Current executable set to '/absolute/path/to/binary' (x86_64).
This change only affects the target create output and does not change
the debugger's behavior. It doesn't resolve symbolic links so it won't
cause confusing when debugging something like clang++ that's symlinked
to clang.

Currently ExecutionContext::GetByteOrder() always returns the host byte

have been omitted by accident. This patch fixes that and adds a unit

Prevent the LoadStoreOptimizer from pairing any load/store instructions with
instructions from the prologue/epilogue if the CFI information has encoded the
operations as separate instructions. This would otherwise lead to a mismatch

Summary:
For functions there is a check to not duplicate the declaration if it is in a
record (class). For function templates there was no similar check, if a
template (in the same class) was imported multiple times the
FunctionTemplateDecl was created multiple times with the same templated
FunctionDecl. This can result in problems with the declaration chain.

- Remove support for non-recursive mutexes. This was unused.
- The std::recursive_mutex is now created/destroyed unconditionally.
Locking is still only done if threading is enabled.
- Alias SmartScopedLock to std::lock_guard.

Summary:
While removing -z separate-code makes lld produce place the code at the
end of a segment right now, it's possible that future changes to the
linker will change that, thereby removing the coverage for the changes
in r367983. This patch adds a linker script to one of the line table
tests, which ensures that the code (and its line table) will be placed
at the very end of a module.

Summary:
Explicitly code-sign the LLDB.framework copy of debugserver in the build-tree. This is necessary, because the Xcode-specific logic in `llvm_codesign` [1] has the side-effect that Xcode code-signs after post-build steps (here: after copying debugserver over into the framework). The special case for Xcode was necessary to avoid double-signing errors in the past (see D55116 and D55816).
