Both the regular and deferred versions of this test contain up to six different test cases: All platforms: * ELF snapshot, using DWARF from the snapshot * ELF snapshot, using DWARF from the separate debugging information For platforms where the test can assemble snapshots: * assembled snapshot, using DWARF from the snapshot or the separate .dSYM package on MacOS * assembled snapshot, using DWARF from the separate debugging information For MacOS only: * creating a single-architecture universal binary from the separate .dSYM package and extracting DWARF information from it * creating a multi-architecture universal binary from the separate .dSYM package and extracting DWARF information from it Originally the tests were written using package:expect, performing program compilation and execution separately before each test and lazily reading DWARF information within the test itself. Since tests using package:expect stop the program immediately on a failure, a failing expectation keeps other independent test cases from being checked. However, it's useful to know if the failure is limited to only a subset of the test cases, since that helps point at which code is to blame for the test failure(s). Now the tests are refactored to first set up the tests by performing all program compilation and execution first, collecting all outputs and DWARF information as test state. Then the test cases are defined over the collected test state using package:test instead of package:expect. This way, as long as there is not a failure in the initial setup, all of the applicable test cases are run even if one or more of them fail. ----- In pkg/native_stack_traces, changes the return types of the reader retrieval methods in the DwarfContainer class and DwarfSnapshot.fromDwarfContainer to be nullable. If the shared object does not contain the expected DWARF information, these methods now return null instead of causing null check exceptions to be thrown.
