940db1b0cf stdlib: remove pthread_attr_t from _stdlib_pthread_create_block 
The attributes were not being used currently.  Since this is a private
interface, remove the parameter as it makes it easier to port to
Windows.

82360c6b27 stdlib: remove pthread_barrier attributes 
These were not in use, and removing this from the signature makes it
possible to re-use the exact signature on Windows more easily.

0693bec1f1 sdlib: rename SwiftPrivatePthreadExtras to SwiftPrivateThreadExtras 
This is in preparation to make the code here more target agnostic for
porting to the Windows threading primitives.  This is used pretty
extensively in the tests, so disabling tests would lose a chunk of
coverage.

e5c1567957 [stdlib] Switch to a stable sort algorithm (#19717) 
This switches the standard library's sort algorithm from an in-place
introsort to use a modified timsort, a stable, adaptive sort that
merges runs using a temporary buffer. This implementation performs
straight merges instead of adopting timsort's galloping strategy.

In addition to maintaining the relative order of equal/non-comparable
elements, this algorithm outperforms the introsort on data with any
intrinsic structure, such as runs of ascending or descending elements
or a significant number of equality collisions.

9bd1a26089 Implementation for SE-0228: Fix ExpressibleByStringInterpolation (#20214) 
* [CodeCompletion] Restrict ancestor search to brace

This change allows ExprParentFinder to restrict certain searches for parents to just AST nodes within the nearest surrounding BraceStmt. In the string interpolation rework, BraceStmts can appear in new places in the AST; this keeps code completion from looking at irrelevant context.

NFC in this commit, but keeps code completion from crashing once TapExpr is introduced.

* Remove test relying on ExpressibleByStringInterpolation being deprecated

Since soon enough, it won’t be anymore.

* [AST] Introduce TapExpr

TapExpr allows a block of code to to be inserted between two expressions, accessing and potentially mutating the result of its subexpression before giving it to its parent expression. It’s roughly equivalent to this function:

  func _tap<T>(_ value: T, do body: (inout T) throws -> Void) rethrows -> T {
    var copy = value
    try body(&copy)
    return copy
  }

Except that it doesn’t use a closure, so no variables are captured and no call frame is (even notionally) added.

This commit does not include tests because nothing in it actually uses TapExpr yet. It will be used by string interpolation.

* SE-0228: Fix ExpressibleByStringInterpolation

This is the bulk of the implementation of the string interpolation rework. It includes a redesigned AST node, new parsing logic, new constraints and post-typechecking code generation, and new standard library types and members.

* [Sema] Rip out typeCheckExpressionShallow()

With new string interpolation in place, it is no longer used by anything in the compiler.

* [Sema] Diagnose invalid StringInterpolationProtocols

StringInterpolationProtocol informally requires conforming types to provide at least one method with the base name “appendInterpolation” with no (or a discardable) return value and visibility at least as broad as the conforming type’s. This change diagnoses an error when a conforming type does not have a method that meets those criteria.

* [Stdlib] Fix map(String.init) source break

Some users, including some in the source compatibility suite, accidentally used init(stringInterpolationSegment:) by writing code like `map(String.init)`. Now that these intializers have been removed, the remaining initializers often end up tying during overload resolution. This change adds several overloads of `String.init(describing:)` which will break these ties in cases where the compiler previously selected `String.init(stringInterpolationSegment:)`.

* [Sema] Make callWitness() take non-mutable arrays

It doesn’t actually need to mutate them.

* [Stdlib] Improve floating-point interpolation performance

This change avoids constructing a String when interpolating a Float, Double, or Float80. Instead, we write the characters to a fixed-size buffer and then append them directly to the string’s storage.

This seems to improve performance for all three types, but especially for Double and Float80, which cannot always fit into a small string when stringified.

* [NameLookup] Improve MemberLookupTable invalidation

In rare cases usually involving generated code, an overload added by an extension in the middle of a file would not be visible below it if the type had lazy members and the same base name had already been referenced above the extension. This change essentially dirties a type’s member lookup table whenever an extension is added to it, ensuring the entries in it will be updated.

This change also includes some debugging improvements for NameLookup.

* [SILOptimizer] XFAIL dead object removal failure

The DeadObjectRemoval pass in SILOptimizer does not currently remove reworked string interpolations as well as the old design because their effects cannot be described by @_effects(readonly). That causes a test failure on Linux. This change temporarily silences that test. The SILOptimizer issue has been filed as SR-9008.

* Confess string interpolation’s source stability sins

* [Parser] Parse empty interpolations

Previously, the parser had an odd asymmetry which caused the same function to accept foo(), but reject “\()”. This change fixes the issue.

Already tested by test/Parse/try.swift, which uses this construct in one of its throwing interpolation tests.

* [Sema] Fix batch-mode-only lazy var bug

The temporary variable used by string interpolation needs to be recontextualized when it’s inserted into a synthesized getter. Fixes a compilation failure in Alamofire.

I’ll probably follow up on this bug a bit more after merging.
