LJ_TRACE updates

eloycoto · eloycoto · commit 5bf5d49b6208 · 2019-07-24T12:20:30.000+02:00
Due to the luajit parameter `hotexit` the lj_trace_exit function will
only happens the number of times that hotexit happens.

This will also probe the `lj_vm_exit_interp` function to make sure that
all luajit function is in there.
