8247251: Assert (_pcs_length == 0 || last_pc()->pc_offset() < pc_offs…

[vnkozlov]

Fix frame state recording for System.arraycopy() intrinsic. This is port of Graal fix:
oracle/graal@438a7cb0257

Graal unit test ArrayCopyIntrinsificationTest.java is updated to catch this case.

I ran tier1 and tier3-graal testing. I also ran CodeCacheInfoOnCompilation/Test.java and c2/Test6603011.java jtreg tests 100 times in Mach5 and got 6 failures with latest JDK. With fix tests passed.
