Instead first try to keep ICs monomorphic if elements kinds generalize. If that fails, use standard polymorphic handling. The Try*PolymorphicAsMonomorphic methods will automatically produce code similar to the previous approach using CheckMapsWithTransitions.

We cannot use set_type() with HType::None() in the HConstant
constructor, since set_type() asserts that the new type is a
subtype of the previous one, but HType::None() is not a subtype
of HType::Tagged() which is the initial type set by the HValue
constructor.

This patch adds an optional type parameter to the HValue,
HInstruction and HTemplateInstruction constructors.

This fixes the result allocation in EmitCreateIteratorResult,

In order to properly sanitize exception data during a 'window.onerror'
handler, we need to know whether a script was served with proper CORS
headers at the time it was loaded into V8. This patch adds a single bool
to ScriptOrigin, and pipes that through the compiler to land on the
Script object. We can then retrieve the parameter when calling the
embedder's exception callback.

Sampling rate is now calculated as total number of samples divided by profiling time in ms. Before the patch the sampling rate was updated once per 100ms which doesn't have any obvious advantage over the simpler method.

Also we are going to get rid of the profile node self and total time calculation in the v8 CPU profiler and only expose profiling start/end time for CpuProfile and number of ticks on each ProfileNode and let clients do all the math should they need it.
