This would ensure that errno value is cleared out before test execution and tests pass even when LIBC_ERRNO_MODE_SYSTEM_INLINE is specified (and errno may be clobbered before test execution). A lot of the tests would fail, however, since errno would end up getting set to EDOM or ERANGE during test execution and never validated before the end of the test. This should be fixed - and errno should be explicitly checked or ignored in all of those cases, but for now add a TODO to address it later (see open issue #135320) and clear out errno in test fixture to avoid test failures.
