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.

This CL adds a bitset to describe the type of IC in each IC slot.
This is necessary for clearing ICs of different types.

With FLAG_vector_ics off (the current state), it's not required because
CALL_IC is the only type of IC in the vector.

Allow reservation of additional input capacity when creating nodes to prevent switching to deque representation when adding well-known additional inputs.

Also ensure that only a single temporary buffer is used to create temporary input arrays before allocating nodes.
