Print more diagnosis info on to-space invariant violation.
Pass the method/field (in GcRootSource) to the read barrier to print
more info when a to-space invariant violation is detected on a
method/field GC root access.
Refactor ConcurrentCopying::AssertToSpaceInvariant().

Refactor and improve GC root handling
Changed GcRoot to use compressed references. Changed root visiting to
use virtual functions instead of function pointers. Changed root visting
interface to be an array of roots instead of a single root at a time.
Added buffered root marking helper to avoid dispatch overhead.
Root marking seems a bit faster on EvaluateAndApplyChanges due to batch
marking. Pause times unaffected.
Mips64 is untested but might work, maybe.

Add hash set
More memory efficient than libcxx since we do not box the values.
Change intern table to use new hash set. Clean up intern table by
removing const casts and deleting unnecessary code.
Changed the class linker to use a hash set, also added a pre-zygote
class table.

Change intern table to unordered set.
Intern table active used bytes goes from 430k to 317k on system
server. Similar %wise savings on other apps.

Add GcRoot to clean up and enforce read barriers.
Introduce a value-type wrapper around Object* for GC roots so that 1)
we won't have to directly add the read barrier code in many places and
2) we can avoid accidentally bypassing/missing read barriers on GC
roots (the GcRoot interface ensures that the read barrier is executed
on a read).
The jdwp test passed.
