compiler/arguments/TestCodeEntryAlignment.java fails on AVX512 machines

```
#
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (/home/jvm/jdk/src/hotspot/cpu/x86/assembler_x86.cpp:12699), pid=8048, tid=8049
# assert(code_section->limit() - code_section->end() > src_len) failed: code buffer not large enough
#
# JRE version: (19.0) (fastdebug build )
# Java VM: OpenJDK 64-Bit Server VM (fastdebug 19-internal-adhoc.jvm.jdk, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:
# V [libjvm.so+0x689ef4] Assembler::popa()+0xf4

This can be reproduced by:
