0a5b3f0727 [TypeChecker] SE-0324: Extend Swift -> C pointer conversions to inout 
Fixes an oversight where `inout` -> C pointer conversion wasn't covered
by implementation of new pointer conversion semantics proposed by SE-0324.

6a65810d30 [Constraint] NFC: Rename ClosureBodyElement to SyntacticElement 
`SyntacticElement` represents a statement, pattern, declaration,
condition, or expression and could originate from i.e. a closure,
a function or a result builder body.

d44d8ec043 Allow Converting Pack Types to Tuples 
Insert an implicit conversion from pack types to tuples with equivalent parallel structure. That means

1) The tuple must have the same arity
2) The tuple may not have any argument labels
3) The tuple may not have any variadic or inout components
4) The tuple must have the same element types as the pack

da36a2cb88 [CS] Restore a type variable for compatibility with rdar://85263844 
Despite being otherwise disconnected from the
constraint system, it's possible for it to affect
how we type-check tuple matches in certain cases.

This is due to the fact that:
- It can have a lower type variable ID than an
opened generic parameter type, so becomes the
representative when merged with it. And because it
has a different locator, this can influence
binding prioritization.
- Tuple subtyping is broken, as it's currently a
*weaker* relationship than conversion.

Therefore, temporarily restore this bit of logic
for language versions < 6. If possible, we should
try and fix tuple subtying in Swift 6 mode to not
accept label mismatches, so that it's not more
permissive than tuple conversion.

497d42d90e [ConstraintSystem] Add a new constraint which connects base with result of the member chain 
The first type represents a result of an unresolved member chain,
and the second type is its base type. This constraint acts almost
like `Equal` but also enforces following semantics:

- It's possible to infer a base from a result type by looking through
  this constraint, but it's only solved when both types are bound.

- If base is a protocol metatype, this constraint becomes a conformance
  check instead of an equality.
