[metadata prespecialization] Only Apple or linux.

nate-chandler · nate-chandler · commit ae1f41e1b2c6 · 2020-02-05T18:06:27.000-08:00
Temporarily disable metadata prespecialization on platforms other than
MacOS, iOS, tvOS, watchOS, or Linux.  At the moment, tests are failing
on Windows with linker errors such as

  demangleToMetadata-558ea9.o : error LNK2001: unresolved external symbol $ss5Int64VN
  demangleToMetadata-558ea9.o : error LNK2001: unresolved external symbol $sSSSHsWP

Once the issue leading to those linker errors has been resolved, the
feature will be enabled on Windows.
