6959014: G1: assert(minimum_desired_capacity <= maximum_desired_capacity) failed: sanity check
Summary: There are a few issues in the code that calculates whether to resize the heap and by how much: a) some calculations can overflow 32-bit size_t's, b) min_desired_capacity is not bounded by the max heap size, and c) the assrt that fires is in the wrong place. The fix also includes some tidying up of the related verbose code.

6975964: G1: print out a more descriptive message for evacuation failure when +PrintGCDetails is set
Summary: we're renaming "evacuation failure" to "to-space overflow". I'm also piggy-backing a small additional change which removes the "Mark closure took..." output.
