7a854ee1cc [CSSimplify] Make solver behavior consistent with TypeCheckPattern for paren patterns 
A single paren pattern becomes a labeled tuple pattern
e.g. `case .test(let value):` should be able to match
`case test(result: Int)`. Note that it also means that:
`cast test(result: (String, Int))` would be matched against
e.g. `case .test((let x, let y))` but that fails during
pattern coercion (behavior consistent with what happens in
`TypeCheckPattern`).

77e6c083f3 [AutoDiff] [CS] Formalize function tupling behavior for @differentiable

cab39bf26c [CS] Formalize param flag handling for imploding params

flags, but carve out exceptions for ownership flags,
which can be thunked, and `@_nonEphemeral` which can
be freely dropped without issue.

af14bba276 [AST] Simplify AnyFunctionType::composeTuple 
Remove the canonicalVararg parameter and
CanParamArrayRef wrapper. Almost none of the
callers want canonicalVararg, and the one that
does calls `getCanonicalType` on the result
anyway.

947a6c32a5 [ConstraintSystem] In the solver, only generate constraints for wrapped 
parameter attributes for closure parameters.

For regular function parameters, these constraints will have already been
generated and solved when computing the backing property wrapper type at
the function declaration. If the solver also generates these constraints
when type checking a function call, it leads to misleading diagnostics
about an argument mismatch that will appear at the function declaration
instead of the call-site.

8c2b88abc0 [CS] Adopt ArgumentList 
- Explicitly limit favoring logic to only handle
unary args, this seems to have always been the
case, but needs to be handled explicitly now that
argument lists aren't exprs
- Update the ConstraintLocator simplification to
handle argument lists
- Store a mapping of locators to argument lists
in the constraint system
- Abstract more logic into a getArgumentLocator
method which retrieves an argument-to-param locator
from an argument anchor expr
