These changes caused a number of issues:
1. No debug info is emitted when a release-debug info compiler is built.
2. OS X deployment target specification is broken.
3. Swift options were broken without any attempt any recreating that
functionality. The specific option in question is --force-optimized-typechecker.
Such refactorings should be done in a fashion that does not break existing
users and use cases.

In 74d979f0ac, the policy was changed
so that only value type accessors are ever marked transparent, and
not class accessors.
This was intended to fix a bug where inlining an accessor of an
Objective-C-derived class across module boundaries caused a linker
failure because the accessor referenced a field offset variable,
which has hidden visibility.
However, this also caused a performance regression for Swift native
classes. Bring back the old behavior for Swift native classes in
non-resilient modules.
Fixes <rdar://problem/29884727>.
After we call into typeCheckExpression() we need to cache the
resulting types in the constraint system type map because we later
call into code that reads the types out of the type map.
Fixes rdar://problem/30376186 as well as a couple crashers.
- Don't allow @_inlineable on stored properties; this generates
invalid SIL since clients can't know about stored properties of
resilient types. Accessors for stored properties of non-resilient
types are already @_inlineable anyway.
- Don't allow @_inlineable on declarations that are not public or
@_versioned, since it's simply redundant.
This patch splits add_swift_library into two functions one which handles
the simple case of adding a library that is part of the compiler being
built and the second handling the more complicated case of "target"
libraries, which may need to build for one or more targets.
The new add_swift_library is built using llvm_add_library, which re-uses
LLVM's CMake modules. In adapting to use LLVM's modules some of
add_swift_library's named parameters have been removed and
LINK_LIBRARIES has changed to LINK_LIBS, and LLVM_LINK_COMPONENTS
changed to LINK_COMPONENTS.
This patch also cleans up libswiftBasic's handling of UUID library and
headers, and how it interfaces with gyb sources.
add_swift_library also no longer has the FILE_DEPENDS parameter, which
doesn't matter because llvm_add_library's DEPENDS parameter has the same
behavior.
@objc inference was looking at unavailable requirements---for which we
don't ever record witnesses---at a point when it is no longer possible
to record such a witness. This is a targeted fix; we need to tackle
the issue of unavailable and optional requirements more thoroughly.
Fixes SR-3917 / rdar://problem/30474860.
Previously we would check TMF_UnwrappingOptional flag, which does not
stick with the constraint, so it would not always persist. Now, add a
new OptionalPayload locator element, which is more correct.
Fixes <rdar://problem/30429709>.
Name lookup can cause import of some Clang declaration, which in turn
need a type checker. Make sure a type checker exists at this time.
This is a baby step toward having the type checker always available,
which is really the end goal. For now, we need this for better generic
environment (de-)serialization.
We don't actually need the TypeLoc for anything, but it was still
getting type-checked, which means it doesn't get the benefit of
inference from the initial value. In some cases the actual type of the
ParamDecl seems to get reset to the TypeLoc's type as well. Just do
the simple thing and set it directly ahead of time.
Fixes a source compatibility issue with Swift 3.0.

If the nested type itself has generic constraints, we would
hit an assertion in requirement inference. Refactor some code
so that we can make the assertion more accurate.
Fixes <rdar://problem/30353095>.
When comparing the parameters of two declarations for the purpose of
partial ordering, it doesn't make sense to compare the parameter
labels: they're dealt with separately and aren't conceptually part of
the type.
This reverts part of #4038 which made the compiler consider it to be an `Explicit` conformance, breaking source code that was accepted in Swift 3.0 which declared a raw type as well as explicit conformance to `RawRepresentable` (reported as rdar://problem/30386658). While I'm here, a couple of spot fixes:
- Ensure an enum's raw value exprs are type-checked before checking conformances of any of its extensions, since the RawRepresentable conformance derivation will blow up if the raw value exprs haven't been checked. Fixes an order dependency issue if `extension Foo: RawRepresentable {}` gets checked before `enum Foo: Int { ... }`.
- Don't display the custom `enum_declares_rawrep_with_raw_type` diagnostic if the source location for the enum's inheritance clause is invalid, so that we don't emit a dislocated diagnostic.
New generic environments should be created directly from the generic
signature, without having to explicitly create an archetype
builder. Now, only the canonical archetype builders are ever used to
create a generic environment.
Clean up the representation of PotentialArchetype in a few small ways:
* Eliminate the GenericTypeParamType* at the root, and instead just
store a GenericParamKey. That makes the potential archetypes
independent of a particular set of generic parameters.
* Give potential archetypes a link back to their owning
ArchetypeBuilder, so we can get contextual information (etc.) when
needed. We can remove the "builder" arguments as a separate step.
Also, collapse getName()/getDebugName()/getFullName() into
getNestedName() and getDebugName(). Generic parameters don't have
"names" per se, so they should only show up in debug dumps.
In support of the former, clean up some of the diagnostics emitted by
the archetype builder that were using 'Identifier' or 'StringRef'
where they should have been using a 'Type' (i.e., the type behind the
dependent archetype).
