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.
