[runtime] Simplify CHECK_OBJECT_COERCIBLE.

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).

Remove inline header includes from non-inline headers (1).

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.

Split function block scoping into a separate flag

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.

Use a new lexical context for sloppy-mode eval

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.

[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.

Rewrite Error.prototype.toString in C++.

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.

Remove several grab-bag includes from the v8.h header.

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.

[turbofan] Remove kInterpreterDispatch CallDescriptor kind in favor of flag.

Rationale: The {kind} of a call descriptor describes what the {target} being
called is--i.e. a JSFunction, code object, or address. That kind materially
dictates the instruction(s) generated for an outgoing call.

The other flags on a call descriptor should describe specific properties
(like whether a roots register is valid or not) so that backend logic doesn't
have to switch over the kind, but is informed directly of what it wants to
know.

Use conservative estimate for GC speed instead of bailing out when computing
mutator utilization.

This makes GC heuristics more robust for small applications that trigger
scavenges but do not trigger full GC.

Fix stale entries in optimized code map.

This fixes a corner-case where extending an optimized code map left
stale entries in the abandoned copy. This can cause havoc not only in
the heap verifier but also in the GC, because stale entries have not
been recorded when being trated weakly.

Note that this also pre-tenures all optimized code maps into old-space
because their lifetime is coupled to the SharedFunctionInfo anyways.

When working on the register allocator, I often need to introspect the various components of the model - e.g. InstructionSequence, Instruction, LiveRange, etc. A pretty printer would help. While we have a suite of operator<< defined for these types, turns out that using them at debug time is close to impossible - gdb has poor (or convoluted) support for instantiating structures (e.g. OFStream, PrintableInstructionSequence, etc), and calling operator<< with pass-by-reference semantics.

I explored gdb macros, but hit an issue quite early with instantiating and initializing an OFStream - "virtual baseclass botch".

Currently, I have a side-file that I include (and then remove before publishing CLs), which defines wrappers to the above operator<< APIs, but this is becoming quite awkward, and I believe the functionality to be quite useful to anyone working in this (regalloc) area, so it's worth having something better than local side-files. The gdb path seems overly-twisted for the problem at hand, and I've noticed elsewhere (e.g. Object) the presence of Print APIs - hence this change.

[es6] Remove Scanner and Parser flags for harmony_modules

These flags weren't doing any real work, since the decision of whether some
source code is a script or module is made outside the parser (currently,
by the V8 API).

The only behavior change in this patch is to always parse 'import' and
'export' as their Token values, which changes the error message from
"Unexpected reserved word" to "Unexpected token import" (which doesn't
seem particularly harmful).
