IntelliJ IDEA 2020.1 EAP with Records/Patterns support

[Remi Forax]

I've forgotten to say that currently the early access build of IDEA doesn't work with java 14 as jdk that run IDEA because in the idea.sh it asks for CMS and CMS have been removed from Java 14. 
I've successfully used G1 or ZGC instead, ZGC seems to provide a smoother experience but it eat more RAMs, I suppose because there is no compress oops support (all references are 64 bits pointers).
