if tests crashed without core dump you will have no clues regarding where, but
this makes tests run a lot faster. Combine with `NVIM_TEST_MAIN_CDEFS` for
maximal speed.
`NVIM_TEST_TRACE_EVERYTHING` (U) (1): by default unit test only record C calls
which is faster then recording everything. Set this variable to 1 if you want to
see all traces.
