Implement TLAB fast paths in artAllocObjectFromCode.

GSS/TLAB GC speedup on N4 (ms):

MemAllocTest 2963 -> 2792
BinaryTrees  2205 -> 2113

Also, measured wth -XX:IgnoreMaxFootprint to invoke GC less often
(only when the bump pointer space is filled rather than based on the
target utilization):

MemAllocTest 2707 -> 2590
BinaryTrees  2023 -> 1906

TODO: implement fast paths for array allocations.
