de51833695 Fix representation of HLoadRoot. 
HLoadRoot doesn't participate in representation inference, and its
represenation is not Tagged at code generation, which leads to incorrect
pointer map assignment and eventual stale pointer access after GC.

6e1ebdcbc3 To aid vector-based load ic work, we need to be able to handle 
the megamorphic load case in hydrogen. A simple approach is to
wrap the probe activity in a hydrogen instruction.

The instruction is novel in that it always tail-calls away.

When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs
will allocate a type vector slot to store feedback information. Full codegen

Support is incomplete, right now the IC doesn't know how to use the feedback

736a17f8f4 ARM: Avoid duplicate vmla when merging vmul and vadd 
Avoid generating duplicate vmla instructions for vmul/vadd sequences where the
vmul has more than one use.

For example: function f(a, b, c) { return (a * b) + c + (a * b); }

Previously, this would produce a vmul for the subexpression (a * b), then vmla
for (a * b) + c, then vmla for (a * b) + [(a * b) + c].

Now it produces vmul, vadd, vadd, as expected.
