[Tarantool-patches] [PATCH luajit 12/19] DynASM: Fix warning.

[Sergey Kaplun]

From: Mike Pall <mike>

(cherry-picked from commit 9b41062156779160b88fe5e1eb1ece1ee1fe6a74)

This patch adds the `/* fallthrough */` comments elsewhere, where it was
missing for the ARM64 build, so the `-Wimplicit-fallthrough` [1] warning
is trigerred.
