This prepares the runtime to be closed with its dependencies when
performing static linking. The pragma ensures that the linker will
automatically pick up the dependent libraries avoiding the need to
explicitly add the dependencies.
We were calling `SymInitialize()` multiple times, which is wrong, which
was making the `SymbolInfo::lookup()` call fail. Also, we weren't
fetching the module names, so we should do that too.

Moved all the threading code to one place. Added explicit support for
Darwin, Linux, Pthreads, C11 threads and Win32 threads, including new
implementations of Once for Linux, Pthreads, C11 and Win32.

We would not previously symbolicate the stack trace and as a result
would not display the stack trace. Add symbolication support to the
runtime to actually make use of the captured stack trace. This allows
us to get a stack trace when the standard library or swift code reports
a fatal error.
The runtime needs this method to initialize the type fields when loading
the images. This was added to the ELF side of the initialization path
but not the COFF side. It repairs the swiftCore.dll build for Windows.
Search through the new section containing Swift protocol descriptor
references to resolve protocols by mangled name. Use this
functionality to support protocol composition types within
_typeForMangledName.
The separate section of type references uses the same type reference format
as in protocol conformance records. As with protocol conformance records,
mangle the type reference kind into the lower two bits. Then, eliminate the
separate "flags" field from the type metadata record. Finally, rename
the section because the Swift 5 stable format for this section is
different from prior formats, and the two runtimes need to be able to
coexist.
The format of protocol conformance records will be changing in Swift 5, so
rename the segment (from, e.g., __swift2_proto to __swift5_proto) to allow
Swift < 5 and Swift 5+ runtimes to coexist.
Restructure the COFF metadata handling to use the linker section
grouping to emit section start/stop markers in the appropriate location.
This allows us to lookup the sections statically without having to the
walk the entire image structure.
Introduce a constructor for PE/COFF binaries. This will ensure that the
registration occurs for all modules appropriately. This should resolve
rdar://problem/19045112. The registration should occur prior to
`DllMain` being invoked from `DllMainCRTStartup`.
