Don't use IS_NULL_OR_UNDEFINED() for CHECK_OBJECT_COERCIBLE() because it
will also return true for undetectable objects, but use IS_NULL() and
IS_UNDEFINED() directly, which will only return true for null or
undefined (which matches the semantics of the abstract operation
CheckObjectCoercible).

This tries to remove includes of "-inl.h" headers from normal ".h"
headers, thereby reducing the chance of any cyclic dependencies and
decreasing the average size of our compilation units.

Note that this change still leaves 7 violations of that rule in the
code. However there now is the "tools/check-inline-includes.sh" tool
detecting such violations.

In an initial attempt to implement sloppy mode lexical bindings,
functions were made lexically scoped in sloppy mode. However, the
ES2015 spec says that they need an additional hoisted var binding,
and further, it's not clear when we'll implement that behavior
or whether it's web-compatible.

This patch splits off function block scoping into a new, separate
flag called --harmony_sloppy_function. This change will enable the
possibility of testing and shipping this feature separately from
other block scoping-related features which don't have the same risks.

In ES6, direct eval() in sloppy mode uses the enclosing function-level
("var") scope for var-style bindings and a new lexical scope for lexical
bindings like let and class. This patch implements that feature by making
lexical bindings that are directly within an EVAL_SCOPE be on the local
scope rather than the enclosing one.

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 avoids many back-and-forth calls to the runtime.

This also slightly changes the way we avoid getters. Previously, we circumvent getting the name property of ReferenceError, SyntaxError and TypeError due to crbug/69187 (in order to avoid leaking information from those errors through a 'name' getter installed on their prototypes). Now we do that for all errors created by V8.

This is the first step of turning the v8.h file into a normal header
instead of an include-the-world header. The new rule is that no other
header files are allowed to include v8.h, which is enforced by DEPS.

Also the number of includes inside the v8.h file has been drastically
reduced. Basically the last missing piece is the inclusion of the big
objects-inl.h file.

This in turn makes many headers follow the IWYU principle.

This is a first step towards constraining down the heap interface to
just the heap.h file. Note that many includes still leak through that
file to the global "src" directory, but there now is a single place
controlling which declarations leak that way. Especially inclusion of
inline header files within "heap" has been limited drastically.
