[jdk18] RFR: 8262134: compiler/uncommontrap/TestDeoptOOM.java failed with "guarantee(false) failed: wrong number of expression stack elements during deopt"

[Dean Long]

C1 patching stubs use the Unpack_reexecute deoptimization type, but if an exception is thrown, that information is lost, causing the VerifyStack logic to fail. Rather than relaxing the VerifyStack logic to accept Unpack_exception in this case, this change sets the reexecute flag on the patch stub call site.
Other changes:
use runtime/BootstrapMethod/BSMCalledTwice.java as a reproducer
improve VerifyStack failure output

-------------

Commit messages:
 - runtime/BootstrapMethod/BSMCalledTwice.java is a reproducer for 8262134
 - print current bytecode if VerifyStack fails
 - set reexecute flag on c1 patching stubs
