This commit disables runtime stack trace dumping via dladdr on Darwin when
asserts are disabled.
This stack trace dumping was added as a way to improve the ability to debug the
compiler for compiler developers. This is all well and good but having such a
feature always enabled prevents us from reducing the size of the swift standard
library by eliminating the swift nlist.

- Revert the use of SWIFT_RUNTIME_EXPORT in ImageInspectionELF.cpp and
fix the unittests by explicitly adding the file to the list
- Revert the change of section data names
If the Swift error wrapped in a _SwiftNativeNSError box conforms to
Hashable, the box now uses the Swift's conformance to Hashable.

...and explicitly mark symbols we export, either for use by executables or for runtime-stdlib interaction. Until the stdlib supports resilience we have to allow programs to link to these SPI symbols.
These should all apply to any Darwin platform, and the current behaviour
was breaking cross-compilation.
Introduces a SWIFT_DARWIN_VARIANTS pattern, to be used as follows:
if(SWIFT_HOST_VARIANT MATCHES "${SWIFT_DARWIN_VARIANTS}")
Also fix one place where I checked the CMAKE_SYSTEM_NAME instead of the
host variant that I recently introduced. I haven't attempted to find
the rest of the places we're doing this though.

- Add frontend and standard library build support for tvOS.
- Add frontend support for watchOS.
watchOS standard library builds are still disabled during SDK bring-up.
To build for TVOS, specify --tvos to build-script.
To build for watchOS, specify --watchos to build-script (not yet supported).
This patch does not include turning on full tests for TVOS or watchOS, and
will be included in a follow-up patch.

Instead of directly referencing a long-dead constructor from the standard library, put a purpose-built function in StdlibUnittest to feed a Swift object reference to the test C code. rdar://problem/18498737

Add functions to dynamically query the extra inhabitants of a single-payload union's payload metadata, then identify or store bit patterns used to represent empty cases, whether they happen to use extra inhabitants or added tag bits.

Whatever difficulty there supposedly was in doing this for Clang must
apply only to standalone builds where no LLVM source is available.
