5736eb0ccb X87: Change the test case for X87 float operations 
The CL https://codereview.chromium.org/1409013004 added / changed some test cases.
       Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result
       check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined
       functions has different behavior comparing with GCC ia32 build and x87 build. The major
       difference is sse float register still has single precision rounding semantic. While X87
       register has no such rounding precsion semantic when directly use register value. The V8
       turbofan JITTed has exactly same result in both X87 and IA32 port.

       So we add the following sentence to do type case to keep the same precision.
          float expect = *i * *j; // *i + *j, etc.

       For test case "RunFloat64MulAndFloat64Add1 / RunFloat64MulAndFloat64Add2 / RunFloat64MulAndFloat64Sub1
       / RunFloat64MulAndFloat64Sub2", the expected result calcaulated by GCC has difference precsion
       when comparing with V8 turbofan result for X87 platform. (Turbofan X87 result is the same as
       IA32 GCC and IA32 Turbofan). So we have to disable those four cases for X87 port.

The BufferedRawMachineAssemblerTester takes care of storing and loading
parameters to and from memory for these test cases. By using the
BufferedRawMachineAssemblerTester the test cases become more readible.

16f133001f Move compiler cctests into v8::internal::compiler namespace. 
This moves all cctest files for the compiler to live in the same
namespace as the components they are testing. Hence we can avoid the
forbidden using directives pulling in entire namespaces.

From the Google C++ style guide: "You may not use a using-directive to
make all names from a namespace available". This would be covered by
presubmit linter checks if build/namespaces were not blacklisted.

c0c214daa8 [Interpreter] Add support for loading from / storing to outer context variables. 
Adds support for loading from and storing to outer context
variables. Also adds support for declaring functions on contexts and
locals. Finally, fixes a couple of issues with StaContextSlot where
we weren't emitting the write barrier and therefore would crash in the
GC.

Also added code so that --print-bytecode will output the
function name before the bytecodes, and replaces MachineType with StoreRepresentation in RawMachineAssembler::Store and updates tests.

This is to support WebAssembly 64-bit ints in the short term, since it
currently uses CheckedLoad/CheckedStore for accesses to the memory. In the

a1b2c275b7 [x64] Match -0 - x with sign bit flip. 
We can use xorps/xorpd on Intel CPUs to flip the sign bit. Ideally we'd
use a RIP-relative 128-bit constant in the code object, as OCaml/GCC
does, however that requires 128-bit alignment for code objects, which is
not yet implemented. So for now we materialize the mask inline.

8dad78cdbd [turbofan] Add backend support for float32 operations. 
This adds the basics necessary to support float32 operations in TurboFan.
The actual functionality required to detect safe float32 operations will
be added based on this later. Therefore this does not affect production
code except for some cleanup/refactoring.

In detail, this patchset contains the following features:
- Add support for float32 operations to arm, arm64, ia32 and x64
  backends.
- Add float32 machine operators.
- Add support for float32 constants to simplified lowering.
- Handle float32 representation for phis in simplified lowering.

In addition, contains the following (related) cleanups:
- Fix/unify naming of backend instructions.
- Use AVX comparisons when available.
- Extend ArchOpcodeField to 9 bits (required for arm64).
- Refactor some code duplication in instruction selectors.

022ea7e057 [turbofan] Unify Math.floor / Math.ceil optimization. 
Provide an intrinsic %MathFloor / %_MathFloor that is used to optimize
both Math.ceil and Math.floor, and use the JS inlining mechanism to
inline Math.ceil into TurboFan code. Although we need to touch code
outside of TurboFan to make this work, this does not affect the way we
handle Math.ceil and/or Math.floor in CrankShaft, because for CrankShaft
the old-style builtin function id based inlining still kicks in first.

Once this solution is stabilized, we can use it for Math.floor as well.
And once that is settled, we can establish it as the unified way to
inline builtins, and get rid of the specialized builtin function id
based inlining at some point.

Note that "builtin" applies to basically every piece of internal
JavaScript/intrinsics based code, so this also applies to the yet to be
defined JavaScript based code stubs and handlers.

496697df4e Add MachineSignature, which is an encapsulation of the machine types for parameters and return values in a graph. 
This utility will be used to simplify Linkage and fix representation inference
to work with graphs where parameters and return values are something other
than tagged. It will also make testing representation inference a lot
easier, since we can then exactly nail down the machine types of parameters
and returns.

This CL also adds c-signature.h, which demonstrates how to convert C function
signatures into MachineSignatures. The CSignatures will be used in tests to
make it easier and simpler to codegen tests.

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize(). 
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.
