In short, there is no more alias command, so you need to create more statics!

static(dmz,inside) 51.88.80.100 172.16.1.100 255.255.255.255
or
static(outside,dmz) 172.16.1.100 51.88.80.100 255.255.255.255

If you have only inside and outside interfaces, your configuration changes a bit. We’ll create two statics per translation. Note that one static is (inside,outside) and the second is (inside,inside). You’ll also need to permit hair pinning on the interface.

static (inside,outside) 75.50.95.178 10.1.0.11 netmask 255.255.255.255 dns 
static (inside,inside) 75.50.95.178 10.1.0.11 netmask 255.255.255.255 dns 

same-security-traffic permit intra-interface

You may also have to append the dns keyword on the end of the static command.
