Allow for the possibility (when the heap is expanding) that the sweep might skip over and past, rather than necessarily step on, the sweep limit determined at the beginning of a concurrent marking cycle.

3b69a96c58 6977924: Changes for 6975078 produce build error with certain gcc versions 
The changes introduced for 6975078 assign badHeapOopVal to the _allocation field in the ResourceObj class. In 32 bit linux builds with certain versions of gcc this assignment will be flagged as an error while compiling allocation.cpp. In 32 bit builds the constant value badHeapOopVal (which is cast to an intptr_t) is negative. The _allocation field is typed as an unsigned intptr_t and gcc catches this as an error.

1f0201f90b 6959014: G1: assert(minimum_desired_capacity <= maximum_desired_capacity) failed: sanity check 
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.

77f845359a 6948538: CMS: BOT walkers can fall into object allocation and initialization cracks 
GC workers now recognize an intermediate transient state of blocks which are allocated but have not yet completed initialization. blk_start() calls do not attempt to determine the size of a block in the transient state, rather waiting for the block to become initialized so that it is safe to query its size. Audited and ensured the order of initialization of object fields (klass, free bit and size) to respect block state transition protocol. Also included some new assertion checking code enabled in debug mode.
