[clang][CFG] Fix compound assignment evaluation order (#212115)
CompoundAssignOperator (e.g. `+=`, `-=`, `<<=`) is a distinct StmtClass
deriving from BinaryOperator, but it was not handled in the CFGBuilder
dispatch switches. As a result it fell through to the generic default
path (VisitChildren over reverse_children), which emits the LHS before
the RHS in the CFG.
Per C++17 [expr.ass]/1, all assignment operators - simple and compound -
sequence the right operand before the left operand. Route
CompoundAssignOperator through VisitBinaryOperator (and
VisitBinaryOperatorForTemporaries), whose existing isAssignmentOp()
branch already emits the RHS before the LHS, matching simple assignment.
This mirrors the class of evaluation-order defect fixed for lambda
captures in f3b31871e9b8.

[libc++][pstl] Implementation of a parallel std::mismatch() based on __pstl::__parallel_find() (#209291)
This PR adds a parallel version of `std::mismatch` as one of the backend
operations.
It also provides an implementation based on `__pstl::__parallel_find()`
which does the heavy lifting.
`libdispatch` and `std_thread` backends expose this implementation under
their backend tags, while the `serial` backend redirects the calls to
the serial `std::mismatch`.
4 flavours of the function are exposed: 3-legged, 3-legged with
predicate, 4-legged, 4-legged with predicate.
3-legged flavours are implemented in the `default` (`composition`)
backend by redirecting the call to the 4-legged flavours.
Included tests check that:
- Semantics of the iterator-only functions is correct.
- Semantics of the predicated functions is correct.

[libc][cpp::string] Allocate fewer temp strings in operator= and += (#210895)
This PR generally updates `cpp::string` to avoid incidental allocations.
Specifically, it:
- Updates `opreator=(string_view)` to avoid allocating a temporary
string:
https://github.com/llvm/llvm-project/blob/67ebc4b221c3e94028b33004cd5cd08deee95048/libc/src/__support/CPP/string.h#L106-L108
- Changes `operator+=(const string&)` to accept a `string_view` so that
strings may be appended without allocation.
- Makes the `string(string_view)` constructor explicit. Before, there
were non-obvious allocations because of the implicit conversion.
As a side effect, this PR has to more carefully handle self-assignment
and self-append. This PR updates append and assignment to avoid calling
`realloc` during append / assignment, as this may invalidate input
pointers held by `string_view` if they point to data held by the string.
This also fixes self-assignment, which previously didn't work, eg
`cpp::string s = "abc"; s = s;` would zero out `s`.
