This takes heap-inl.h out of the "Giant Include Cluster".
Naturally, that means adding a bunch of explicit includes
in a bunch of places that relied on transitively including
them before.
As of this patch, no header file outside src/heap/ includes
heap-inl.h.

The following runtime functions (and their intrinsic counter parts) are
completely unused/obsolete by now
- %ToInteger
- %GeneratorGetInputOrDebugPos
and in addition the intrinsics for %_ToNumber and %_IsJSProxy are also
dead (according to code coverage and manual verification), so drop them
as well (their runtime function counterparts are still somewhat used).

The HasProperty builtin differed in its expected argument order from
the HasProperty runtime function. Like all other related spec
primitives (e.g.: GetProperty, SetProperty, DeleteProperty), it should
take {object} as the first argument and {key} as the second.
This CL changes the builtin and all related spots to use the correct
order.
There was also a tricky bug in interpreter intrinsic rewriting, which
assumes (but does not verify) that the argument order between runtime
function and builtin is identical. Besides cctests, HasProperty
intrinsic rewriting seems to be dead code.

The parameter indices are shifted by 1 in BytecodeArrayBuilder
because the receiver is variable at index 0 and not -1.
Split BytecodeArrayBuilder::Parameter(index) method into
Receiver() (same as Parameter(-1)) and
Parameter(index).
This way we avoid confusing (index+1) counting in BytecodeGenerator().

There are only a few occasions where we allocate a register in an outer
expression allocation scope, which makes the costly free-list approach
of the BytecodeRegisterAllocator unecessary. This CL replaces all
occurrences with moves to the accumulator and stores to a register
allocated in the correct scope. By doing this, we can simplify the
BytecodeRegisterAllocator to be a simple bump-pointer allocator
with registers released in the same order as allocated.
The following changes are also made:
- Make BytecodeRegisterOptimizer able to use registers which have been
unallocated, but not yet reused
- Remove RegisterExpressionResultScope and rename
AccumulatorExpressionResultScope to ValueExpressionResultScope
- Introduce RegisterList to represent consecutive register
allocations, and use this for operands to call bytecodes.
By avoiding the free-list handling, this gives another couple of
percent on CodeLoad.

Introduce a new machine operator Float64Pow that for now is backed by
the existing MathPowStub to start the unification of Math.pow, and at
the same time address the main performance issue that TurboFan still has
with the imaging-darkroom benchmark in Kraken.
Also migrate the Math.pow builtin itself to a TurboFan builtin and
remove a few hundred lines of hand-written platform code for special
handling of the fullcodegen Math.pow version.
