Oops, we missed one...

http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/builds/5542/steps/ninja%20check%201/logs/FAIL%3A%20Clang%3A%3Aarm_acle.c

// AArch32: call void @llvm.write_register.i32(metadata !5, i32 %1)
<stdin>:465:7: note: possible intended match here
 tail call void @llvm.write_register.i32(metadata !5, i32 %0)

Either change it to a wildcard {{.*}} or create a variable if you need it later.

Also, have a look around for more cases where this may be problematic
in the future.
