[12] RFR(S): 8207247 AARCH64: Enable Minimal and Client VM builds

[Aleksei Voitylov]

Hi,

please review this patch which adds Minimal and Client VM support to 
AARCH64 port.

Enhancement: https://bugs.openjdk.java.net/browse/JDK-8207247
Webrev: http://cr.openjdk.java.net/~avoitylov/webrev.8207247.01

Tested by running hotspot regression tests on Server, Client and Minimal 
on AARCH64. No new issues compared to other architectures were found. 
Please keep in mind Minimal VM includes C1 and Serial GC only, and does 
not include JMX. With that:

du -b lib/minimal/libjvm.so
4091984    lib/minimal/libjvm.so

Thanks,

-Aleksei
