Hello,

Original RFE: https://bugs.openjdk.java.net/browse/JDK-8248870

aarch64_ad.m4 and aarch64.ad are decorated slightly different in 11u,
unmodified ubfizIConvI2LAndI code was inserted similarly after
ubfizIConvI2L taking that into account, benchmark part applied cleanly.

11u webrev: http://cr.openjdk.java.net/~dchuyko/8248870/webrev.11u.00/

Testing: tier1, tier2.
