[9] RFR (L): JDK-8055903: Develop sanity tests on SPARC's SHA instructions support

[Filipp Zhinkin]

Hi all,

please review sanity tests on SHA intrinsics support.

Tests verify that appropriate intrinsic is emitted whencorresponding
option is enabled and not emitted ifsuch option is disabled.

In case when CPU does not support required instructions or
JVM configuration does not allow to use an intrinsic,
the test will expect that intrinsic will not be emitted.

Bug id: https://bugs.openjdk.java.net/browse/JDK-8055903
Webrev: http://cr.openjdk.java.net/~fzhinkin/8055903/webrev.00/
Testing: manual, automated.

Thanks,
Filipp.
