In Linux. Instead of setting temporary "fallback" RUNPATH, Set
LD_LIBRARY_PATH to builder's runtime when building standard library.
So we don't need to strip the temporary RUNPATH when installing.
For compiling codes required for macro support, we now need swiftc
compiler in the build machine.
Unlike Darwin OSes, where swiftCore runtime is guaranteed to be present
in /usr/lib, Linux doesn't have ABI stability and the stdlib of the
build machine is not at the specific location. So the built compiler
cannot relies on the shared object in the toolchain.
Fixes a regression caused by https://github.com/apple/swift/pull/67636 in which
the patterns for case statements generated to match unavailable enum elements
were missing a type. The missing type caused a crash during SILGen if the
unavailable element case was the first one in the swtich statement.

Deleting instructions which produce such values could result in
shortening the lifetime of a move-only value. This is illegal because
according to language rules, the lifetime of move-only values is fixed.

Owned lifetime canonicalization bails on move-only values.
Previously, though, every value that was fed to canonicalization was
then attempted to be deleted. For dead move-only values, the result
could be to shorten move-only lifetimes, which is illegal per language
rules.
Here, this is fixed by not attempting to delete owned values for which
canonicalization bailed.

As with property wrappers, we can't properly desugar the application of
accessor macros to bindings with multiple variables. Prohibit them up
front.
Fixes rdar://112783811.
In any nominal declaration or extension thereof that is produced by a
macro expansion, make sure we perform qualified name lookup when
resolving operators so that we're guaranteed to find the
macro-introduced operators. Otherwise, expanding a macro that defines
a new type with conformances involving operators doesn't work.

Trivial enum cases in a memory location don't need to be destroyed.
Don't require that the store to such a memory location is statically known as a trivial enum case.
Instead just require that it's below a switch_enum successor for a trivial case.
Fixes a false alarm.

Don't print the uses of freestanding declaration macros in Swift
interfaces. Instead, print the declarations they produce, as
appropriate.
Fixes rdar://113730928.
If the substitution terms of a concrete type symbol contain unresolved
name symbols, we have an invalid requirement that is dropped from the
minimized signature. In this case, the rewrite system used for minimization
cannot be installed as the official rewrite system for this generic
signature, because building a rewrite system from the signature will
produce a different result.
This might be the cause of the crash in rdar://114111159.
For now, always use indirect convention for types with packs. This is
motivated by the fact that getting from/setting to a pack currently
requires addresses which aren't materialized for tuples. In the
fullness of time, these values should be direct in opaque values mode,
but for now it can be postponed.
Previously both `AreAllStoredPropertiesDefaultInitableRequest`
and `HasMemberwiseInitRequest` checked only "current" properties
of the type but macro expansions can add new stored and/or
init accessor properties that affect this logic so we need to
make sure that macro expansions happen and new properties are
accounted for.
Note that the original idea was to use `getStoredProperties()`
but that runs into multiple circularity issues related to lazy
properties.
