RFR (XXS): 8132728: Memory leak in MethodHandles::verify_ref_kind function(fastdebug build)

[Vladimir Kozlov]

Looks good.

Note, it is not real memory leak - code does not return from STOP call. It either produce assert and exit or wait to 
attach debugger (ShowMessageBoxOnError). See MacroAssembler::debug64() for example.

Thanks,
Vladimir
