6627787: CMS: JVM refuses to start up with -Xms16m -Xmx16m
7000125: CMS: Anti-monotone young gen sizing with respect to maximum whole heap size specification
7027529: CMS: retire CMSUseOldDefaults flag
Summary: Simplify CMS heap sizing code, relying on ergonomic initial sizing consistent with other collectors for the most part, controlling only young gen sizing to rein in pause times. Make CMS young gen sizing default statically cpu-dependant. Remove inconsistencies wrt generation sizing and policy code, allowing for the fixing for 6627787 and 7000125. For 7027529, retire the flag CMSUseOldDefaults which had been introduced as a bridge from JDK 5 to JDK 6 a number of years ago.

Summary: Bulk zeroing reduction didn't work with G1, because arraycopy would call pre-barriers on uninitialized oops. The solution is to have version of arraycopy stubs that don't have pre-barriers. Also refactored arraycopy stubs generation on SPARC to be more readable and reduced the number of stubs necessary in some cases.

Summary: Normally compressed oops is enabled when the maximum heap size is under a certain limit, except when G1 is also enabled. Remove this limitation. Also re-enable GCBasher testing with G1 on 64 bit windows in jprt.

Summary: 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.
