[jdk11u-dev] RFR: 8283059: Uninitialized warning in check_code.c with GCC 11.2

Fri Apr 28 20:49:55 UTC 2023

I backport this for parity with 11.0.20-oracle.

The patch did not apply cleanly. There was a conflict with a prior warning-elimination fix (JDK-8266168). Though it first appears as if this PR would revert the previous fix, it is a more elaborate solution.

SAP-internal test suite passes on multiple (actually on all tested) platforms.

Reviews are very much appreciated.
