JDK-8252049 - Native memory leak in ciMethodData ctor
Description
Debian folks report that Zero m68k (and seems only that arch) fails the static assert added by JDK-8252049. It affects at least JDK 16, but would affect more releases once JDK-8252049 is backported.

/<<PKGBUILDDIR>>/src/hotspot/share/oops/methodData.hpp: In constructor 'MethodData::CompilerCounters::CompilerCounters()':
/<<PKGBUILDDIR>>/src/hotspot/share/oops/methodData.hpp:1987:55: error: static assertion failed: align
 1987 |       static_assert(sizeof(_trap_hist) % HeapWordSize == 0, "align");

There is a second instance where it fails after patching the first instance: === Output from failing command(s) repeated here === * For target hotspot_variant-zero_libjvm_objs_ciMethodData.o: /<<PKGBUILDDIR>>/src/hotspot/share/ci/ciMethodData.cpp: In member function 'void ciMethodData::load_data()': /<<PKGBUILDDIR>>/src/hotspot/share/ci/ciMethodData.cpp:205:46: error: static assertion failed: align 205 | static_assert(sizeof(_orig) % HeapWordSize == 0, "align"); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~ * All command lines available in /<<PKGBUILDDIR>>/build/make-support/failure-logs. === End of repeated output ===
