0841f7241b Track usage of "this" and "arguments" in Scope 
This adds flags in Scope to track wheter a Scope uses "this" and,
"arguments". The information is exposed via Scope::uses_this(),
and Scope::uses_arguments(), respectively. Flags for tracking
usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().

Knowing whether scopes use "this" and "arguments" will be handy
to generate the code needed to capture their values when generating
the code for arrow functions.

CallICs have had some confused tracing, because the IC state is not
entirely captured by the installed code stub - it lives in the type
vector.

Change tracing to be able to use the vector state changes instead.

Also split v8-core independent methods from checks.h to base/logging.h and
merge v8checks with the rest of checks.

The CPU::FlushICache method is moved to CpuFeatures::FlushICache

RoundUp and related methods are moved to base/macros.h

Remove all layering violations from src/libplatform

Important notices:

- The snapshot cannot be created for big-endian target in cross-compilation
  environment on little-endian host using simulator.

- In order to have i18n support working on big-endian target, the icudt46b.dat and
  icudt46b_dat.S files should be generated and upstreamed to ICU repo.

- The mjsunit 'nans' test is endian dependent, it is skipped for mips target.

- The zlib and Mandreel from Octane 2.0 benchmark are endian dependent due to
  use of typed arrays.

2b1da67263 Implement Math.random() purely in JavaScript. 
This removes tons of architecture-specific code and makes it easy to
experiment with other pseudo-RNG algorithms. The crankshafted code is
extremely good, keeping all things unboxed and doing only minimal
checks, so it is basically equivalent to the handwritten code.

When benchmarks are run without parallel recompilation, we get a few
percent regression on SunSpider's string-validate-input and
string-base64, but these benchmarks run so fast that the overall
SunSpider score is hardly affected and within the usual jitter. Note
that these benchmarks actually run even faster when we don't
crankshaft at all on the main thread (the regression is not caused by
bad code, it is caused by Crankshaft needing a few hundred microsecond
for compilation of a trivial function). Luckily, when parallel
recompilation is enabled, i.e. in the browser, we see no regression at
all!

Make V8_INT64_C() and V8_UINT64_C() available in 32-bit mode as well,
so we can write readable constants (base 10) instead of having to
obfuscate them using V8_2PART_UINT64_C().

7a2c253e24 Move OS/compiler/feature detection to public v8config.h header. 
From now on the v8config.h header should be the one and
only file where we do (freaky) checks to detect OS, C++
compiler or certain compiler features. Since we need that
both internally and for the public API, the new v8config.h
is the proper place to add (everything is prefixed with V8_
so we are safe).

Safe operations are those that either do not observe unsignedness or have special support for uint32 values:

- all binary bitwise operations: they perform ToInt32 on inputs;
- >> and << shifts: they perform ToInt32 on left hand side and ToUint32 on right hand side;
- >>> shift: it performs ToUint32 on both inputs;
- stores to integer external arrays (not pixel, float or double ones): these stores are "bitwise";
- HChange: special support added for conversions of uint32 values to double and tagged values;
- HSimulate: special support added for deoptimization with uint32 values in registers and stack slots;
- HPhi: phis that have only safe uses and only uint32 operands are uint32 themselves.

0a7010458a Remove the static qualifier from functions in header files. 
This shaves 416+ KB, just under 1% off the size of the debug d8 executable
on Linux (mostly because the CheckHelper functions for assertions were
getting separate copies for each compilation unit).  The difference in
release builds is negligible---a size reduction of 0.1%.

Also, change namespace-level 'static const' variables to remove the static
storage class as it's the default.

1e9a7267ab Introduce extended mode. 
This CL introduces a third mode next to the non-strict
(henceforth called 'classic mode') and 'strict mode'
which is called 'extended mode' as in the current
ES.next specification drafts. The extended mode is based on
the 'strict mode' and adds new functionality to it. This
means that most of the semantics of these two modes
coincide.

The 'extended mode' is entered instead of the 'strict mode'
during parsing when using the 'strict mode' directive
"use strict" and when the the harmony-scoping flag is
active. This should be changed once it is fully specified how the 'extended mode' is entered.

This change introduces a new 3 valued enum LanguageMode
(see globals.h) corresponding to the modes which is mostly
used by the frontend code. This includes the following
components:
* (Pre)Parser
* Compiler
* SharedFunctionInfo, Scope and ScopeInfo
* runtime functions: StoreContextSlot,
  ResolvePossiblyDirectEval, InitializeVarGlobal,
  DeclareGlobals

The old enum StrictModeFlag is still used in the backend
when the distinction between the 'strict mode' and the 'extended mode' does not matter. This includes:
* SetProperty runtime function, Delete builtin
* StoreIC and KeyedStoreIC
* StubCache

81e7f597b0 Reintroduce duplicate identifier detection in preparser. 
Duplicate identifier detection must be an early syntax error in strict code,
so errors in otherwise lazily compiled functions must be caught in the
preparser.

Originally introduced in r8541 and reverted in r8542.
Now really compiles on Windows.

2531480d10 Re-establish mips basic infrastructure. 
This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

TEST=none
BUG=none

589eb4a861 Add CODE_POINTER_ALIGN, use it in Page to align generated code. 
The object's space in Page starts after Page header and is aligned to kMapAlignment which is 32 bytes on 32-bit and 8 bytes on 64-bit.

In case of 64-bit target, the current page header size is exactly 32 bytes so we get the code magically aligned at 32 bytes but it is better to have a separate CODE_POINTER_ALIGN macro to make sure the object space in Page is aligned properly for both maps and code.

There could be a small waste of bytes sometimes (since both Page header and Code header sizes are aligned separately) but it seems the optimal one would involve cross-dependencies between .h files and not clear if it's worth it.

This is a back-port from Isolates branch.

e61bd7bd26 ARM: backend opt for ToBoolean: JIT code generation for ToBool 
Upgraded the CodeGenerator::ToBoolean() function in the ARM backend to use complete JIT code generation and not make runtime calls to ToBool (when VFP is enabled). 

This change also includes the vcmp VFP instruction that supports a constant 0.0 as the second operand.

The static ScopeInfo members moved into this class.
The new class is named ScopeInfoObject which I am not proud of,
better ideas are very welcome.

Also got rid of the sentinels in the serialized scope info which saves 3 words per function
and is not slower.

675e711f1c Cardmarking writebarrier. 
- New сardmarking write barrier handles large objects and normal objects in a similar fashion (no more additional space for pointer tracking is required, no conditional branches in WB code).
- Changes to enable oldspaces iteration without maps decoding:
-- layout change for FixedArrays: length is stored as a smis (initial patch by
Kevin Millikin)
-- layout change for SharedFunctionInfo: integer fields are stored as smi on
arm, ia32 and rearranged on x64.
-- layout change for String: meaning of LSB bit is fliped (1 now means hash not
computed); on x64 padding is added.
-- layout of maps is _not_ changed. Map space is currently iterated in a special
way.
