[lilliput-jdk17u:lilliput] RFR: 8304331: [Lilliput/JDK17] Fix RTM locking

[Roman Kennke]

Some RTM locking tests are currently failing:

compiler/rtm/cli/TestUseRTMLockingOptionWithBiasedLocking.java
compiler/rtm/locking/TestRTMRetryCount.java
compiler/rtm/locking/TestRTMTotalCountIncrRate.java
compiler/rtm/locking/TestUseRTMAfterLockInflation.java
compiler/rtm/locking/TestUseRTMForInflatedLocks.java
compiler/rtm/locking/TestUseRTMForStackLocks.java
compiler/rtm/method_options/TestUseRTMLockElidingOption.java

Most are because there's a jmpb in UseRTMLocking parts that fails because of longer locking code with Lilliput. One test is failing because it checks a warning message when somebody tries +UseBiasedLocking together with RTM locking, but Lilliput forces biased locking to be off, so the warning never appears. I problem-listed that test.

Testing:
 - [x] all tests listed above
