SwiftCompilerSources: add Context.notifyDependency(onBodyOf:)
...
It notifies the pass manager that the optimization result of the current pass depends on the body (i.e. SIL instructions) of another function than the currently optimized one.

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.
