v2.0.0-beta208

New features

• Adding FiberRef.IsRunning with convenient bindings
• Experimenting with usage of yield in while loops. The following code can be used to prevent possible infinite loops without yielding control:

do {
...
} while(yield std.NextTrue())

Optimizations

• Resolving all module's type refs during module loading so that there's no runtime resolving during VM execution
• Storing all constants as an array in compiled module not as a List for less access overhead
• Getting rid of unnecessary type casting when visiting blocks
• Using less abstractions: getting rid of IDeferSupport and IBranchyCoroutine
• Converting ClassSymbol._all_members to an array instead of SymbolStorage

Bug fixes

• Fixing potential bug in TaskManager.RemoveAt(..)
