RFR: JDK-8324341 : Remove redundant preprocessor #if's checks

Fri May 24 02:06:14 UTC 2024

Can I please get some reviews for this change to remove some redundant #if / #ifdefs ?

My search was just a simple grep + some bash script, though. I tested using JTREG on MacOS, Linux Mariner & Alpine from tier1 to 3.
