da3f583492 Add mark_dependence [unresolved] 
In preparation for inserting mark_dependence instructions for lifetime
dependencies early, immediately after SILGen. That will simplify the
implementation of borrowed arguments.

Marking them unresolved is needed to make OSSA verification
conservative until lifetime dependence diagnostics runs.

86f23b089f SIL: add the [perf_constraint] flag in SILFunction 
Specifies that the optimizer and IRGen must not add runtime calls which are not in the function originally.
This attribute is set for functions with performance constraints or functions which are called from functions with performance.

7fb4fc0f36 MandatoryPerformanceOptimizations: fix the linkage of function-signature-specialized functions 
We need to keep the original linkage because it would be illegal to call a shared not-serialized function from a serialized function.

Also, rename the API to create the specialized function.

bd7db677ed MandatoryPerformanceOptimizations: perform function signature optimization to remove metatype arguments 
Generic specialization already takes care of removing metatype arguments of generic functions.
But sometimes non-generic functions have metatype arguments which must be removed.
We need handle this case with a function signature optimization.

This enables, for example, to use `OptionSet` in embedded swift.

eb626c2814 ObjectOutliner: don't outline objects with tail allocations

6b046a14eb StackPromotion: prevent resilient classes from being stack promoted. 
Usually resilient classes cannot be promoted anyway, because their initializers are not visible and let the object appear to escape.
But in some rare situations this check is needed.

return `Instruction.memoryEffects` in the face of escaping.
