RFR (trivial): 8219519: Remove linux_sparc.ad and linux_aarch64.ad

[Jie Fu]

Hi Tobias,

Thanks a lot for your review.

It's a bit difficult for me to test this patch since I don't have a 
sparc or arm machine.
I've analyzed the adlc processing logic in 
make/hotspot/gensrc/GensrcAdlc.gmk finding that ad-files under 
./src/hotspot/os_cpu/$(HOTSPOT_TARGET_OS)_$(HOTSPOT_TARGET_CPU_ARCH) are 
optional.
Since both linux_sparc.ad and linux_aarch64.ad are useless for the 
generation of C2, it would be better to remove them.

I'll try my best to test it.

By the way, I really appreciate If someone with sparc or aarch64 
development environment could help to verify this change.
Thanks in advance.

Best regards,
Jie
