Merge branch 'aronisstav/dialyzer/dialyzer_tests/OTP-9116' into dev
* aronisstav/dialyzer/dialyzer_tests/OTP-9116:
Increase timetrap of options1 suite
Write output_plt even when plt_check is ok
Create plt with erts, kernel and stdlib only
Update test results as they currently appear in dev
Major restructure of dialyzer's testsuite
Add 'apps' option to the erlang interface
Update spec file to work with new common test structure
Test suites for Dialyzer
