d59d7ffc4a 6985015: C1 needs to support compressed oops
This change implements compressed oops for C1 for x64 and sparc. The changes are mostly on the codegen level, with a few exceptions when we do access things outside of the heap that are uncompressed from the IR. Compressed oops are now also enabled with tiered.

36b4f60585 7001363: java/dyn/InvokeDynamic should not be a well-known class in the JVM

Using r12 as temporary register around call_VM trashes heapbase becausecall_VM doesn't always return immediately to following code (eg forward_exception, popframe and early return support).

e5344b854c 6978187: G1: assert(ParallelGCThreads> 1 || n_yielded() == _hrrs->occupied()) strikes again
An evacuation failure while copying the roots caused an object, A, to be forwarded to itself. During the subsequent RSet updating a reference to A was processed causing the reference to be added to the RSet of A's heap region. As a result of adding to the remembered set we ran into the issue described in 6930581 - the sparse table expanded and the RSet scanning code walked the cards in one instance of RHashTable (_cur) while the occupied() counts the cards in the expanded table (_next).

fe147ae592 6997298: fatal error: must own lock CMS_markBitMap_lock during heap dump
Since we are at a stop-world pause, the existing CMS-phase checks are sufficient for safety, and the locking check can be safely elided. Elaborated documentation comment to the case where class unloading and verification are disabled, and the query happens when we aren't in the sweeping phase, where the answer "false" would be (almost everywhere) too pessimistic.
