We need to ignore such casts because otherwise the constructed walking path wouldn't contain the right `existential` field kind.
Fixes a miscompile caused by redundant load elimination.

inlining, generic/closure specialization, and devirtualization optimization passes.
SILFunction::canBeInlinedIntoCaller now exlicitly requires a caller's SerializedKind_t arg.
isAnySerialized() is added as a convenience function that checks if [serialized] or [serialized_for_pkg].
Resolves rdar://128704752
The OSSA elimination pass has not yet been moved below all high level
function passes. Until that work has been completed the Autodiff
closure-spec optimization pass cannot solely support OSSA instructions.
Add PartialApplyInst.hasNoescapeCapture
Add PartialApplyInst.mayEscape
Refactor DiagnoseInvalidEscapingCaptures. This may change functionality because tuples containing a noescape closure are now correctly recognized. Although I'm not sure such tupes can ever be captured directly.
SILBoxTypes have their own generic signature and substitution
map. This means that every time we query isEscapable or mayEscape, we
need to extract the type of the box's field and perform type
substitution so that the AST query only sees types from the function's
generic environment.
Fixes rdar://124179106 (Assertion failed in SIL:
(!type->hasTypeParameter() && "caller forgot to mapTypeIntoContext!"))
Provide APIs needed by lifetime dependence diagnostics, namely LifetimeDependenceConvention.
Reorganize the APIs so it's easy to find related functionality which
API is responsible for which functionality.
Remove the originalFunctionConvention complexity. It is no longer
needed for lifetime dependence inference, and generally should be
avoided in SIL.
Add some placeholder FIXMEs because this not a good PR in which to
change existing functionality.
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.
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.
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.
