cb911cf098 6946892: c1 shouldn't sign-extend to upper 32bits on x64 
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.

Removed scan only regions and associated code. The young portion of the collection set is now constructed incrementally - when a young region is retired as the current allocation region it is added to the collection set.

These changes include a check that causes retained to-space regions that are now tagged as humongous to be disregarded and a new to-space region allocated.
