- Correctly construct cmake cmdline for wasmstdlib including cmake common host options. This is required in order to include e.g. `CMAKE_OSX_SYSROOT` on macOS, etc.
- Ensure we're passing path to newly-built SDK to sil-opt
This makes almost every AutoDiff tests passing for Wasm target (the only exception is `AutoDiff/validation-test/always_emit_into_client/multi_module_struct_no_jvp.swift` as `expectCrash()` is not working properly on Wasm.
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.
