clang-p2996/llvm/test/CodeGen/AArch64/bf16-shuffle.ll
Fangrui Song 3d18c8cd26 [test] Replace aarch64-*-{eabi,gnueabi}{,hf} with aarch64 
Similar to d39b4ce3ce
Using "eabi" or "gnueabi" for aarch64 targets is a common mistake and
warned by Clang Driver. We want to avoid them elsewhere as well. Just
use the common "aarch64" without other triple components.
