6946892: c1 shouldn't sign-extend to upper 32bits on x64 Summary: c1 does sign-extension when it loads ints and shorts from memory to 64-bit registers. This causes problems for c2 because it relies on the fact the int passed in a 64-bit register is zero-extended. Reviewed-by: never

6939027: G1: assertion failure during the concurrent phase of cleanup Summary: The outgoing region map is not maintained properly and it's causing an assert failure. Given that we don't actually use it, I'm removing it. I'm piggy-backing a small change on this which removes a message that it's printed before a Full GC when DisableExplicitGC is set.

6943926: G1: Integer overflow during heap region verification Summary: The expression that calculates the live bytes for a heap region can overflow for a suitably large humongous region/object. Cache the object size in a suitably sized local variable so that the expression is converted to a wider type. Reviewed-by: tonyp, jmasa, iveresov, apetrusenko
