[jdk11u-dev] RFR: 8263776: [JVMCI] add helper to perform Java upcalls

Mon Aug 23 14:21:41 UTC 2021

Here is a backport for JDK-8263776. The patch doesn't apply cleanly since it uses features only introduced with JDK-8230199 (JDK 15+, not in OpenJDK 11u). This patch is the same labsopenjdk 11 uses. This patch is also needed for using graal js with plain OpenJDK.

Testing: test/hotspot/jtreg/compiler/jvmci and manual upstream Graal unit test.
