Hence, I mentioned that jit.opt.start call makes the test more robust.

Indeed. We just check, that all compiler phases are dumped (so all
necessary modules are successfully loaded). Thanks for noticing, I've
updated the commit message the following way:
| Since commit c9d88d5f48054d78727b587fef7567422cdc39a6 ('Fix #984: add
| jit.* library to the binary') all required modules implemented in Lua
| are bundled (i.e. compiled into the executable as a C literal) into
| Tarantool binary. While making Tarantool work on ARM64 platforms, it
| turned out the arch-specific module (namely, jit/dis_arm64.lua) is not
| bundled. Within this patch the missing sources are added and jit.dump
| works fine on ARM64 hosts as a result.

Great, thanks!
