8276711: compiler/codecache/cli tests failing when SegmentedCodeCache used with -Xint

[eastig]

Clean backport to have a non-segmented CodeCache for JVM running with -XX:TieredStopAtLevel=0 -XX:+SegmentedCodeCache. The fix has been in mainline for 1.5 years.
Risks are low: the fix prevents the allocation of the non-profiled code heap which is not used in the interpreter-only mode.

Additional testing:

• Linux x86_64 fastdebug: tier1
• Linux x86_64 fastdebug: tier2
• Linux x86_64 fastdebug: tier3
• Linux AArch64 fastdebug: tier1
• Linux AArch64 fastdebug: tier2
• Linux AArch64 fastdebug: tier3
