RFR: JDK-8211105: AArch64: Disable cos/sin and log intrinsics in jdk11u pending fix

[Andrew Dinn]

Can I please get a review for this trivial fix for jdk11u which is
intended to disable the broken, generated AArch64 trig and log
intrinsics. This is a stop-gap to avoid the breakage until we are ok to
backport upstream fixes.
