These tests were XPASS-ing on Linux bots creating Mach-O, which makes
sense, since the real difference is the object format.
I'm hoping a short-term fix to get these tests passing on ELF is to
create two copies of the runtime -- one built with -fPIC, and one
without. A follow-up patch will change clang's driver to pick between
them depending on whether `-shared` is specified.

According to the buildbots, the new features for shared objects don't
work on ELF since it requires an -fPIC when building the profile
library. XFAIL these tests for now.
It's possible we'll have to build two versions of the profile library on
Linux (one with -fPIC and one without), but it's not clear to me exactly
how to resolve this.

Change the API of the instrumented profiling library to work with shared
objects.
- Most things are now declared hidden, so that each executable gets
its own copy.
- Initialization hooks up a linked list of writers.
- The raw format with shared objects that are profiled consists of a
concatenated series of profiles. llvm-profdata knows how to deal
with that since r208938.
