[libc++] Add move constructor & assignment to `exception_ptr` (#164281)
This commit adds move constructor, move assignment and `swap`
to `exception_ptr`. Adding those operators allows us to avoid
unnecessary calls to `__cxa_{inc,dec}rement_refcount`.
Performance results (from libc++'s CI):
```
Benchmark Baseline Candidate Difference % Difference
------------------------------------ ---------- ----------- ------------ --------------
bm_exception_ptr_copy_assign_nonnull 9.77 9.94 0.18 1.79%
bm_exception_ptr_copy_assign_null 10.29 10.65 0.35 3.42%
bm_exception_ptr_copy_ctor_nonnull 7.02 7.01 -0.01 -0.13%
bm_exception_ptr_copy_ctor_null 10.54 10.60 0.06 0.56%
bm_exception_ptr_move_assign_nonnull 16.92 13.76 -3.16 -18.70%
bm_exception_ptr_move_assign_null 10.61 10.76 0.14 1.36%
bm_exception_ptr_move_ctor_nonnull 13.31 10.25 -3.06 -23.02%
bm_exception_ptr_move_ctor_null 10.28 7.30 -2.98 -28.95%
bm_exception_ptr_swap_nonnull 19.22 0.63 -18.59 -96.74%
bm_exception_ptr_swap_null 20.02 7.79 -12.23 -61.07%
```
As expected, the `bm_exception_ptr_copy_*` benchmarks are not influenced by
this change. `bm_exception_ptr_move_*` benefits between 18% and 30%. The
`bm_exception_ptr_swap_*` tests show the biggest improvements since multiple
calls to the copy constructor are replaced by a simple pointer swap.
While `bm_exception_ptr_move_assign_null` did not show a regression in the CI
measurements, local measurements showed a regression from 3.98 to 4.71, i.e. by
18%. This is due to the additional `__tmp` inside `operator=`. The destructor
of `__other` is a no-op after the move because `__other.__ptr` will be a
nullptr. However, the compiler does not realize this, since the destructor is
not inlined and is lacking a fast-path. As such, the swap-based implementation
leads to an additional destructor call. `bm_exception_ptr_move_assign_nonnull`
still benefits because the swap-based move constructor avoids unnecessary
__cxa_{in,de}crement_refcount calls. As soon as we inline the destructor, this
regression should disappear again.
Works towards #44892

-----------
[Clang] FunctionEffects: properly extract the type of a bound member member function from a CallExpr. (#166101)
There's a bug illustrated by this example:
```
template <typename T>
struct Holder {
T value;
T& operator*() { return value; }
};
struct X {
using Dispatch = float (X::*)() [[clang::nonblocking]];
void fails(Holder<Dispatch>& holder) [[clang::nonblocking]]
{
(this->*(*holder))(); <<< the expression is incorrectly determined not to be nonblocking
}
void succeeds(Holder<Dispatch>& holder) [[clang::nonblocking]]
{
auto func = *holder;
(this->*func)();
}
};
```
In both cases we have a `CXXMemberCallExpr`. In `succeeds`, the
expression refers to a `Decl` (`func`) and gets a useful PTMF type. In
`fails`, the expression does not refer to a `Decl` and its type is
special, printed as `bound member function`. `Expr` provides a method
for extracting the true type so we can use that in this situation.
