When adding profiling instrumentation, use libclang_rt.profile_tvos.a
for TVOS targets and libclang_rt.profile_watchos.a for WatchOS targets.
I've also fixed up a comment and added an assert() that prevents us from
defaulting to an incorrect platform.

The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.

Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib
shouldn't prevent it from being linked. This makes Darwin behave like
other toolchains, and link in the profile runtime irrespective of
-nostdlib, since the resulting program can't be run unless you link
this.
I've also added a test to show that other toolchains already behave
like this.

This change removes libclang_rt.profile-pic-<arch>.a version of
profile runtime. Instead, it's sufficient to always build
libclang_rt.profile-<arch>.a with -fPIC, as it can be linked into
both executables and shared objects.

If `-shared` is specified, pull in a PIC-version of the profile runtime,
which was added to compiler-rt in r208947. I'm hoping this will get the
bots on my side.
