We can use tag dispatching to distinguish between the synchronized and
non-synchronized accessors. Also eliminated the need of adding explicit
"synchronized" in the name when using the macros.
As a note, we currently have one case of using both relaxed and
synchronized accessors (Map::instance_descriptors).
Cleaned up:
* BytecodeArray::source_position_table
* Code::code_data_container
* Code::source_position_table
* FunctionTemplateInfo::call_code
* Map::instance_descriptors
* Map::layout_descriptor
* SharedFunctionInfo::function_data

This CL was generated by an automatic clang AST rewriter using this
matcher expression:
callExpr(
callee(
cxxMethodDecl(
hasName("operator->"),
ofClass(isSameOrDerivedFrom("v8::internal::Object"))
)
),
argumentCountIs(1)
)
The "->" at the expression location was then rewritten to ".".

- Replaces Utf8Decoder with something based on ValueOfIncremental +
NonAsciiStart and moves it into v8/internal.
- Internalizes utf8 strings by first converting them to one or two byte
- Removes IsUtf8EqualsTo and replaces current uses with IsOneByteEqualsTo

This patch gives DescriptorArray its own visitor id and its
own layout that is independent from the layout of WeakFixedArray.
This allows us to use raw 16-bit integers for keeping track of
the number of descriptors (total, non-slack, and marked).
As a side-effect, we save one word per descriptor array on 64-bit.

There is no good reason to have the meat of most objects' initialization
logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead,
this CL changes the protocol between Heap and Factory to be AllocateRaw,
and all object initialization work after (possibly retried) successful
raw allocation happens in the Factory.
This saves about 20KB of binary size on x64.

This CL creates the invariant that the BigInt class treats
BigInt objects as immutable. Writing to new BigInt objects
as part of their construction is done by the MutableBigInt
helper class, which in turn is hidden as an implementation
detail in bigint.cc.
As a side effect, this refactoring enforces right-trimming
checks for all newly created BigInts, and ensures that all
BigInt allocations possibly exceeding kMaxLength check for
this case and throw a RangeError instead of crashing.

Rebuilding (after touching certain files) is crazy slow because
includes are out of control. Many of these files we need to rebuild are
cctests which pull in more includes than they need.
