RFR(M): 8166140: C1: Possible integer overflow in LIRGenerator::generate_address on several platforms

[Doerr, Martin]

Hi,

as discussed with Vladimir, C1 contains code to simplify constant index/displacement addressing which uses int. However, int may overflow on 64 bit platforms.

Please review the following webrev:

I'll also need a sponsor, please.

Thanks and best regards,
Martin
