[PATCH] D50782: [XRay][compiler-rt] Avoid InternalAlloc(...) in Profiling Mode

[Dean Michael Berris via Phabricator via llvm-commits]

We avoid using dynamic memory allocated with the internal allocator in
the profile collection service used by profiling mode. We use aligned
storage for globals and in-struct storage of objects we dynamically
initialize.

What we haven't removed yet is the use of the `Vector<...>` type, which
internally may be using the internal allocator implementation, which we
can migrate to using the `Array<...>` type instead.

This change partially addresses llvm.org/PR38577.
