.NET Process Launched,
An ICorProfiler implementation that is interested in GC events is attached later that
An allocation happened.

This change does not impact the profiler launch scenario, and nothing can be worse than a crash in the profiler attach scenario.
IMPORTANT: Is this backport for a servicing release? If so and this change touches code that ships in a NuGet package, please make certain that you have added any necessary package authoring and gotten it explicitly reviewed.
