[11] RFR(S): 8198987: [Graal] compiler/intrinsics/sha/sanity tests fail on macos with Graal as JIT

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8198987
http://cr.openjdk.java.net/~thartmann/8198987/webrev.00/

Although Graal supports SHA intrinsics [1], the test uses LogCompilation to determine if the
intrinsics were emitted which is not supported by Graal. Also, the test does not check if the SHA
intrinsics are actually available. It also fails if C2 is used and the intrinsics are disabled via
-XX:DisableIntrinsic=_sha_implCompress,_sha2_implCompress,_sha5_implCompress.

Similar to the mathexact tests (see JDK-8182727), we should use the isIntrinsicAvailable WhiteBox
API method. It currently always returns false for Graal as JIT (Graal has its own unit tests for
intrinsics).

Thanks,
Tobias
