New congruence enumeration benchmark

Add a cross-encoding version of strcmp, use it in bridged String equality, and expose it for Foundation's use ( #87271 )
...
There's a longstanding problem in implementing `-isEqualToString:`,
where if you don't know how to get fast access to the other NSString's
contents, you have to pick between doing it character by character (very
slow), or calling [other isEqualToString: self], which risks infinite
recursion if the other string does the same.
This cuts the gordian knot by adding a new method
`isEqualToBytes:encoding:count:`, so you can get the contents out of
`self`, and hand it to the other string, confident that it will not need
to (nor, in fact be able to) ask you anything that might recurse.

[Concurrency] Improve performance of task groups
...
rdar://172192966
The tasks of a task group were stored in a singly linked list, causing a
linear scan for a task to find its predecessor, whenever a task completed
and had to be removed from the list. This change turns it into a doubly
linked list, so the linear scan is avoided completely.

[Concurrency] make enqueue forwarding chain inlinable ( #87611 )
...
The inlinable certainly wont hurt on these "forwarding" methods, though
I was not able to confirm a noticable difference at least using this
benchmark.
Since adding those is definitely good anyway, I didn't dig much further,
let's just add them.
Assisted by: claude to make the benchmark, manually verified all changes
ran benchmarks and checked results etc

This benchmark just wants to test if stack promotion of an array literal works.

Add contains(_:) methods to (Closed)Range ( #76891 )
...
The _StringProcessing module provides a generic, collection-based
`contains` method that performs poorly for ranges and closed ranges.
This addresses the primary issue by providing concrete overloads
for Range and ClosedRange which match the expected performance for
these operations.
This change also fixes an issue with the existing range overlap tests.
The generated `(Closed)Range.overlap` tests are ignoring the "other"
range type when generating ranges for testing, so all overlap tests
are only being run against ranges of the same type. This fixes things
so that heterogeneous testing is included.
