2a68eee5f1 xprop: Test fixes and abort on test failure 
Use `$finish(0)` to silently exit even when using recent iverlog
versions. Run `write_verilog -noexpr` before `write_verilog` as the
latter can modify the design.

This also enables checking the tests results, as xprop should be in a
state where the existing tests pass.

26a6c60478 Add test for typenames using constants shadowed later on 
This possible edge case came up while reviewing #3555. It is currently
handled correctly, but there is no clear test coverage.

6d021f04d4 tests: Fix path of yosys invocation in xprop tests 
For now xprop test failures are still expected and ignored, but without
this change, they did not even run unless the yosys build was in path.

777c589e85 Handle range offsets in packed arrays within packed structs 
This brings the metadata for packed arrays in packed structs
in line with the metadata for unpacked arrays, and correctly
handles the case when both lsb and msb in an address range are
non-zero.
