6a769ac1df [presubmit] Enable readability/namespace linter checking.
This enables linter checking for "readability/namespace" violations
during presubmit and instead marks the few known exceptions that we
allow explicitly.

8e634eaa0b Make some foo.h headers usable without foo-inl.h header.
This CL us a pure refactoring that makes an empty compilation unit
including just "foo.h" but not "foo-inl.h" compile without warnings or
errors. This is needed to further reduce the header dependency tangle.

6c743b2b39 [runtime] Store constructor function index on primitive maps.
This way we can greatly simplify the different variants of ToObject in
our codebase and make them more uniform and robust.  Adding a new
primitive doesn't require finding and changing all those places again,
but it is sufficient to setup the constructor function index when
allocating the map.

We use the inobject properties field of Map, which is invalid primitive
maps anyway.

This means something like new Float32Array([23, 42]) will be allocated on heap.

b74cfe4a8f LayoutDescriptorHelper is now able to calculate the length of contiguous regions of tagged/non-tagged fields.
This functionality is now used by both object visitor and store buffer.

f133ac501b In-object double fields unboxing (for 64-bit only).
This CL introduces LayoutDescriptor which is responsible for tracking which in-object fields are tagged and which are not.
LayoutDescriptor field added to Map. Currently unboxing is disabled.
