Unfortunately, it's undocumented. I think it's a remnant from some old MIPS assemblers.

I'm actually starting to have doubts about supporting .asciiz in LLVM.

I've grepped the Linux kernel and I've found only 2 uses of .asciiz, both in MIPS assembly,
while .asciz is used a lot more, in many different architectures, including MIPS (only once, but that means it's not a compatibility issue).
FreeBSD has a few more uses of .asciiz (about 8, all of them in MIPS assembly), but .asciz still outnumbers .asciiz.

It might be worth it to try to push Linux and FreeBSD to switch to .asciz for MIPS assembly, but, on the other hand, .asciiz is not difficult to support, just a bit ugly.
