This seems to only manifest with GCC 11+:

```
* For target hotspot_variant-server_libjvm_objs_assembler_aarch64.o:

/home/shade/trunks/jdk/src/hotspot/cpu/aarch64/assembler_aarch64.cpp:140:7: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the 'else'

```

JDK-8294438 missed this spot, because it was tested with GCC 10.
