Erik Eckstein 7cceaff5f3 SIL: don't print operand types in textual SIL
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.
