[8u] Request for approval for 8170873 - PPC64: Poor StrictMath performance due to non-optimized compilation

[Seán Coffey]

Gustavo,

Have your jdk8u-dev edits been reviewed anywhere ? Any differences from 
the jdk 9 fix mean it requires a review. Please resubmit your backport 
approval request once that's available.

regards,
Sean.
