185820a148 Fix sign of fractional units in Duration initializers from Double. (#66582) 
* Fix sign of fractional units in Duration initializers from Double.

When separating a double duration into integral and fractional parts, we got the sign wrong. This fixes that bug.

* Fixup variable name.

8124738fc2 [stdlib] Fix calling convention mismatch for debugger utility functions 
The functions `swift_retainCount`, `swift_unownedRetainCount`, and
`swift_weakRetainCount` are declared in `HeapObject.h` as using
the C calling convention, but the Swift declarations referenced them
by `@_silgen_name`, which uses the Swift calling convention. This
patch fixes the mismatch without any ABI/API breakage by calling the
utility functions through C interop.

db0a7287a5 Rework the .seconds, .milliseconds, and .microseconds constructors to preserve exact values (#66111) 
When constructing a Duration from Double, we should do it in such a way that exact integer inputs are preserved exactly, so long as they are represented as a Duration. This was not previously the case. Now it is.

23c19333df [stdlib] Fix String.reserveCapacity underallocation (#65902) 
When called on a string that is not uniquely referenced,
`String.reserveCapacity(_:)` ignores the current capacity, using
the passed-in capacity for the size of its new storage. This can
result in an underallocation and write past the end of the new
buffer.

This fix changes the new size calculation to use the current UTF-8
count as the minimum. Non-native or non-unique strings
now allocate the requested capacity (or space enough for the
current contents, if that's larger than what's requested).

`_diagnoseUnavailableCodeReached()` at the beginning of the function to cause
it to trap if executed at run time.

5d43f75173 stdlib: force inlining of ContiguousArray.endIndex and ContiguousArray._getCount 
This let the optimizer generate efficient code for generic array loops (note that generic functions are not inlined by default).
Note that the same change is not done for `Array` because this might increase code size due to Array's bridging code.

Nate Chandler
cda365ca8d [stdlib] Collection types are eagerMove. 
Types that have "value semantics" should not have lexical lifetimes.
Value types are not expected to have custom deinits. Are not expected to
expose unsafe interior pointers. And cannot have weak references because
they are structs. Therefore, deinitialization barriers are irrelevant.
