Subject: [PATCH] Gale Reduce array allocations
License: GPL-3.0-only (https://www.gnu.org/licenses/gpl-3.0.html)
Gale - https://github.com/GaleMC/Gale
Enum's values returns anew array copy of the enums, this behavior is defined in
`src/jdk.compiler/share/classes/com/sun/tools/javac/comp/Lower.java#visitEnumDef`
This is a defensive programming strategy to prevent enums from being modified. However,
copying is unnecessary if we only have read calls.
So we can cache the values result to avoid useless allocations.
Cached as the array since it does not create iterator on the enhanced for loop,
But the list does, and may spend more time than iterating using the array.
One-time calls are excluded from this patch, since no need.
The JMH benchmark of this patch can be found in SunBox's `CachedEnumValuesForLoop`
This patch is based on the following patch:
"reduce allocs"
