AArch64.
Arm can mean AArch32 (often written as "ARM").

Use `--target=` for new tests. `--target=aarch64` is sufficient and preferred
for generic ELF features.

// CHECK-NOOPT-NOT: "-fsplit-machine-functions"
+// CHECK-AARCH64: "-fsplit-machine-functions"
// CHECK-TRIPLE: error: unsupported option '-fsplit-machine-functions' for
target
----------------
Just reuse CHECK-OPT
