[PATCH] D31413: [libc++] Use __attribute__((init_priority(101))) to ensure streams get initialized early

[Eric Fiselier via Phabricator via cfe-commits]

EricWF created this revision.

This patch fixes http://llvm.org/PR28954 using the `init_priority` attribute. All supported compilers accept this attribute, including clang-cl.
I'm only putting this up for review because IDK how to write a test for it.

Can anybody suggest a way to test this?
