Type annotations for instruction operands are omitted, e.g.
```
%3 = struct $S(%1, %2)
```
Operand types are redundant anyway and were only used for sanity checking in the SIL parser.
But: operand types _are_ printed if the definition of the operand value was not printed yet.
This happens:
* if the block with the definition appears after the block where the operand's instruction is located
* if a block or instruction is printed in isolation, e.g. in a debugger
The old behavior can be restored with `-Xllvm -sil-print-types`.
This option is added to many existing test files which check for operand types in their check-lines.
Previously we gave them the same SIL linkage as the method, then changed
the LLVM IR linkage to 'internal' (which is roughly equivalent to
SIL 'private') in IRGen.
This would crash in the SIL verifier if an @objc method was
'@_alwaysEmitIntoClient'. While such a combination of attributes is
silly since '@objc' methods are intrinsically part of the ABI, we
should not crash in this case.
The simplest fix is to just set the linkage to private at the SIL
level, avoiding the IRGen hack entirely.
Commit to a command line option spelling so that build systems can
start testing it. I deliberately picked one of the longer names we
were considering because we can always decide to add a shorter alias,
but can't decide a shorter name was too generic.
Like the other supplementary output flags,
-emit-parseable-module-interface-path will emit a .swiftinterface file
to a particular path, while -emit-parseable-module-interface will put
it next to the main output (the one specified with -o).
rdar://problem/43776945
* [InterfaceGen] Only print 'mutating' and 'nonmutating' on accessors
* Add SILGen test for usage of dynamic accessors in and out of interfaces
* Add -enable-objc-interop to dynamic_accessors test
