9691060418 [Diagnostics] Add declaration name to macro_attached_to_invalid_decl 
This could also use `%kind` for the declaration kind, but that ends up
being "extension of struct" instead of just "extension", which seems
slightly worse.

18cb5f4f3d [Diagnostics] Update in_macro_expansion note for attached macros 
Use the attached atttribute's location as the location of the macro,
rather than the location of the declaration it's attached to. Also add
the kind and name of that declaration to the note itself.

f0f74e6c5e [Macros] Don't allow types to shadow freestanding macros. 
When performing name lookup for freestanding macros (e.g., after the
`#`), don't allow types to shadow macros from imported libraries.

Fixes rdar://110429368.

aee071bf4e Introduce an experimental @_rawLayout attribute. 
This attribute can be attached to a noncopyable struct to specify that its
storage is raw, meaning the type definition is (with some limitations)
able to do as it pleases with the storage. This provides a basis for
implementing types for things like atomics, locks, and data structures
that use inline storage to store conditionally-initialized values.
The example in `test/Prototypes/UnfairLock.swift` demonstrates the use
of a raw layout type to wrap Darwin's `os_unfair_lock` APIs, allowing
a lock value to be stored inside of classes or other types without
needing a separate allocation, and using the borrow model to enforce
safe access to lock-guarded storage.

200563c2e6 Option: add -libc as an option for Swift tools 
Ensure that we process `-libc` in `swift-symbolgraph-extract` and
`swift-api-extract`.  This option is used by Windows to determine the C
ABI to use and thus impacts the ABI exposed by the ClangImporter to the
Swift interface.  This partially enables the use of
`swift package dump-symbol-graph` on Windows.

5b3c34b9e7 fix a linking problem in swift-frontend 
Sometimes when building the SwiftCompilerSources with a host compiler, linking fails with unresolved symbols for DenseMap and unique_ptr destroys.
This looks like a problem with C++ interop: the compiler thinks that destructors for some Analysis classes are materialized in the SwiftCompilerSources, but they are not.
Explicitly defining those destructors fixes the problem.

4d20423e00 Optimizer: re-implement the RedundantLoadElimination pass in Swift 
The new implementation has several benefits compared to the old C++ implementation:

* It is significantly simpler. It optimizes each load separately instead of all at once with bit-field based dataflow.
* It's using alias analysis more accurately which enables more loads to be optimized
* It avoids inserting additional copies in OSSA

The algorithm is a data flow analysis which starts at the original load and searches for preceding stores or loads by following the control flow in backward direction.
The preceding stores and loads provide the "available values" with which the original load can be replaced.
