I added a workaround for disassembly non-determinism in dotnet#255. See dotnet#255 for details of what causes the non-determinism. It turns it relied on a reflection hole that allowed init-only static fields to be modified after static constructor has been called. That hole was fixed in dotnet/runtime#37849 so the workaround is no longer valid and causes an exception from pmi. I don't see a way to work around the non-determinism without changing framework code so for now I'm just reverting the workaround. Unfortunately, that means that we can get non-deterministic disassembly for any method that inlines System.Threading.Thread.GetCurrentProcessorId. Fixes dotnet#271.

I added a workaround for disassembly non-determinism in #255.
See #255 for details of what causes the non-determinism.
It turns out it relied on a reflection hole that allowed
init-only static fields to be modified after static constructor has
been called. That hole was fixed in dotnet/runtime#37849
so the workaround is no longer valid and causes an exception from pmi.
I don't see a way to work around the non-determinism without changing
framework code so for now I'm just reverting the workaround. Unfortunately, that
means that we can get non-deterministic disassembly for any method that inlines
System.Threading.Thread.GetCurrentProcessorId.
Fixes #271.
