Changing the nextArg value of MethodHandlesTest to be bigger than
Integer.MAX_VALUE to actually test long arguments reveals a bug on
There were actually two bugs:
1. For i2l and unboxi long values were stored in two slots as 32-bit
words instead of a 64-bit one.
2. The stack-move conversion value was read as 32-bit value and then
shifted which resulted in e.g. 0xffffffff values in 64-bit registers
instead of -1.
