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.
This change ensures all store_borrows are ended with an end_borrow, and uses of the store_borrow
destination are all in the enclosing store_borrow scope and via the store_borrow return address.
Fix tests to reflect new store_borrow pattern
The SILGen testsuite consists of valid Swift code covering most language
features. We use these tests to verify that no unknown nodes are in the
file's libSyntax tree. That way we will (hopefully) catch any future
changes or additions to the language which are not implemented in
libSyntax.
I am going to leave in the infrastructure around this just in case. But there is
no reason to keep this in the tests themselves. I can always just revert this
and I don't think merge conflicts are likely due to previous work I did around
the tooling for this.
Otherwise, the plus_zero_* tests will have plus_zero_* as a module name, causing
massive FileCheck problems.
The reason why I am doing it with the main tests is so that I can use it when
syncing branches/etc.

I don't think any of this was necessary anymore, and
I suspect it was working around other related issues
that have since been fixed.
Whatever we did to 'self' here we also would have
had to do for extension methods anyway.
Note that some tests changed but I believe the end
result should be equivalent.
Fixes SR-613, a miscompile that caused an overrelease of "self" when partially applying a protocol method to a generic or existential of a refined class-constrained protocol.
