8242310: use reproducible random in hotspot compiler tests

[GoeLin]

I backport this for parity with 11.0.16-oracle.

I had to adapt the change in some places, all quite trivial:

TestTrichotomyExpressions.java
TestShift.java
Vec_MulAddS2I.java
These tests are not in 11. Skipped.

ClearDirectivesFileStackTest.java
Resolved Copyright.

UnsafeIntrinsicsTest.java
A later change doubling the test description was already backported.
Applying the patch was trivial.
