The following errors come up when compiling v8
with clang 3.7 on FreeBSD/amd64:

Moves the creation of the interpreter table early on during initialization
to ensure that even on nosnap builds it still gets allocated in the

TurboFan is now a requirement and supported by all backends, so we don't
need those macros (plus all the machinery on top) anymore.

When a (prototype) map registers as a user of its own prototype, it now remembers the index in that prototype's registry where it is listed.
This remembered index is used on un-registration to find the right slot to clear without walking the entire registry.
Compaction of the registry must update all entries' remembered indices.

Note that this tests performed unnecessary many iterations which led to
long runtimes in debug mode and also caused flaky GCs during that would
cause the optimized code map to be flushed and violated assumptions.

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.

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).

This is only an estimate since it counts objects that could be shared,
for example strings, cow arrays, heap numbers, etc.
It however ignores objects that could be shared, but may only be used
by the context to be measured, for example shared function infos,
script objects, scope infos, etc.

This introduces a CopyFixedArrayAndGrow method on Factory that takes
the "grow amount" instead of the "new size" as an argument. The new
interface is safer because it allows for mutations by the GC that
potentially trim the source array.
This also fixes a bug in SharedFunctionInfo::AddToOptimizedCodeMap
where the aformentioned scenario led to unused entries within the
optimized code map.
Note that FixedArray::CopySize is hereby deprecated because it is
considered unsafe and should no longer be used.

Store arity in FormalParameters; store name (instead of var) and is_rest flag in individual parameters. Ensure that the arity is always maintained consistently.
This is preparation for more parameter destructuring adjustments. In particular, a follow-up CL will separate parameter recording from declaring the variables.

There is only one use case for it: String.prototype.search converts a
string argument into a RegExp. The cache is used to avoid repeating that
conversion. However, this does not make the added complexity worthwhile.

The BytecodeArrayBuilder has responsibility for emitting the BytecodeArray. It will be used by the AST walker.
Bytecode now uses an accumulator plus registers rather being pure register based.

Since we need the notion of a dummy vector ic, we can use that to avoid
a special case of the IC constructor. Also, consolidate the two dummy
ICs into one.

--harmony_sloppy includes behavior to turn on sloppy mode lexical
bindings. Before this patch, it also included a way to parse let
which is likely web-incompatible (let is disallowed as an
identifier). This patch splits off the let parsing from the more
general block scoping code, so that block scoping can be developed
independently.

- Ensure frame_size is always set during allocation.
- Add DCHECKs that frame_size is a valid value
- Remove locals_count, which we don't need yet (possibly every)
- Add a newline at the end of BytecodeArray::Dissassemble
for each bytecode.
