RFR: 8340110: Ubsan: verifier.cpp:2043:19: runtime error: shift exponent 100 is too large for 32-bit type 'int'

[Afshin Zafari]

The value 100 for shift comes from a test which shuffles the bytecode contents and tries to verify the resulting bytecode. So, the solution is first check if there is no error in verification then use left-shift to find the type of the class being verified.
