90a7f07489 Implement loop variable assignment analysis. 
This analysis computes the set of variables that are assigned in each loop. This is useful to avoid creating redundant loop phis when building an SSA graph, which just waste memory and require analysis to get rid of.

This CL implements an AST walk for the analysis and plugs the result into the TurboFan graph builder. I left this analysis under a flag for A/B testing and until sufficient unit tests can be developed.

a2e21393ed Introduce FeedbackNexus for vector-based ics. 
A FeedbackNexus is the combination of a feedback vector, a slot(s) in
the vector, along with methods to query and manipulate that information
in a type-correct way.

A CallIC will have a CallICNexus, a LoadIC a LoadICNexus, etc.,
reflecting the fact that different types of ICs configure their data
in unique ways.

This CL limits itself to introducing and using the nexus type only for
CallICs. A follow-up will use them for Load and KeyedLoadICs for the
case when the --vector-ics flag is turned on.

The notion of a Nexus is also embedded at the lowest level of the IC
class. This makes sense because more ICs should become vector-based
in the future.

05effbaadf Make NextCodeLink pointer 8-byte aligned after GC pointer updating uses atomics. 
After r24737 pointer updating is done by atomic operations which strictly
require target address to be 8-byte alignment on MIPS64.

The alignment is broken on 64-bit arches because InstructionSize is first field
and has Int size.

Order of fields in object layout are changed to make kNextCodeLinkOffset
divisible by 8. The size of code object header remains the same.
