Hotspot jtreg GC tests throws assert on clientvm fastdebug ARM32 build. Number of failing tests: 63

The assertion is reproduced on clientVM only. ServerVM build is Ok.
The assertion is reproduced on fastdebug, but on release build displacement value is the same, it just generates instruction with wrong offset silently!

How to reproduce:
  jtreg-5.0/bin/jtreg -v -jdk:clientvm-jdk-15/fastdebug/ -dir:test_sources/test/hotspot/jtreg/gc TestAgeOutput.java

The actual wrong displasement value is 259. Originally it comes from LIR_Address::LIR_Address(InstanceKlass::reference_type_offset):
