Refactor lithium classes to reduce the number of virtual functions.
...
This reduces the binary size by making the Is* type-test functions non-virtual.
I had to change Gap and Label instructions to have a common abstract superclass because both act as gap-instructions for the register allocator.

Enable GVN for polymorphic loads by not expanding them at the HIR level.
...
This change adds a new IR instruction for polymorphic loads. It performs
map compares and loads in one IR instruction instead of splitting each
load into a graph of map-compares and field loads.
The advantage is a smaller IR and less basic blocks, plus it allows to
do GVN on polymorphic loads.

Refactor polymorphic load and inline function graph construction.
...
Change the way we construct the graph for polymorphic loads to match that of
polymorphic stores.
Introduce a stack-allocated helper for saving and restoring all the
function-specific graph builder state that needs to change when we begin
translating an inlined function. Make this class authoritative by moving
redundant state out of the builder and deferring to the current function's
state.
Ensure that we always print a tracing message when abandoning an inlining
attempt.
