bc99986cf9 SIL: add a dependency token operand to global_addr 
Optionally, the dependency to the initialization of the global can be specified with a dependency token `depends_on <token>`.
This is usually a `builtin "once"` which calls the initializer for the global variable.

264cbaea42 Add mark_dependence [nonescaping] flag. 
The dependent 'value' may be marked 'nonescaping', which guarantees that the
lifetime dependence is statically enforceable. In this case, the compiler
must be able to follow all values forwarded from the dependent 'value', and
recognize all final (non-forwarded, non-escaping) use points. This implies
that `findPointerEscape` is false. A diagnostic pass checks that the
incoming SIL to verify that these use points are all initially within the
'base' lifetime. Regular 'mark_dependence' semantics ensure that
optimizations cannot violate the lifetime dependence after diagnostics.

2128c21106 Migrate SwiftCompilerSources to FunctionConvention. 
Layers:
- FunctionConvention: AST FunctionType: results, parameters
- ArgumentConventions: SIL function arguments
- ApplyOperandConventions: applied operands

The meaning of an integer index is determined by the collection
type. All the mapping between the various indices (results,
parameters, SIL argument, applied arguments) is restricted to the
collection type that owns that mapping. Remove the concept of a
"caller argument index".

MemoryLifetimeVerifier: use CalleeCache instead of AliasAnalysis

0897d8a720 MemoryLifetimeVerifier: use CalleeCache instead of AliasAnalysis 
To verify if a function may read from an indirect argument, don't use AliasAnalysis.
Instead use the CalleeCache to get the list of callees of an apply instruction.
Then use a simple call-back into the swift Function to check if a callee has any relevant memory effect set.

This avoids a dependency from SIL to the Optimizer.
It fixes a linker error when building some unit tests in debug.

fc534e1c28 SwiftCompilerSources: better APIs for handling resilient nominal types 
* add `NominalTypeDecl.isResilient`

* make the return type of `Type.getNominalFields` optional and return nil in case the nominal type is resilient.
This forces users of this API to think about what to do in case the nominal type is resilient.
