Hi Ivo,

  Thanks very much for testing this on SPARC platform.

  What's really reused is the DWARF CFA number 0x2d behind
DW_CFA_GNU_window_save.  It is in vendor extension space (
DW_CFA_lo_user.. DW_CFA_hi_user) so the semantics depends on vendor
interpreation.

Maybe the commit log could/should be simplified, because
I was confused too.

Doesn't the Aarch64 version of the opcode have its own
name, like DW_CFA_GNU_Aarch64_whatever, even if it reuses the
opcode number?  I think that would help a lot going forward
if it had one.  E.g., it'd avoid confusion, allow for easier
searching, etc.

Introducing Aarch64 specific name would be very much appreciated.
+1 here!
I.
