[jfx15] RFR: Request to sync July 2020 CPU changes into jfx

[Kevin Rushforth]

Johan and Phil,

I request approval to sync changes from to the just-released July 2020 
CPU release into the 'jfx15' branch of the 'jfx' repo. Here is the 
aggregate set of changes for the fixes:

https://github.com/kevinrushforth/jfx/compare/e2d1c02...cpu-2007-sync

NOTE: Since this is an integration of already-reviewed fixes into the 
jfx15 branch of the jfx repo, I will push it directly rather than via a 
pull request.
