This way, many files which only need CompilationInfo but not compiler.h
and its dependencies can include just compilation-info.h.

Rebuilding (after touching certain files) is crazy slow because
includes are out of control.
Fixing it:
- Don't include stuff in headers unless necessary.
- Include the stuff you need, not some other stuff that happens to include the
stuff you need.

The BufferedRawMachineAssemblerTester caused problems for the
Int64Lowering. Instead we construct a TF graph now which is compiled by
Pipeline::GenerateCodeForTesting.

If the architecture does not provide rounding instructions, then C
implementations of these rounding instructions are called. The C
implementations from math.h are used, function pointers are registered
as external references so that they can be call from the simulator.

MachineType is now a class with two enum fields:
- MachineRepresentation
- MachineSemantic
Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably:
- register allocator now uses just the representation.
- Phi and Select nodes only refer to representations.

This change does not change how the BufferedRawMachineAssemblerTester is
used in tests, but it makes its construction in other constructors (e.g.
in the WasmRunner) cleaner.

This utility makes it possible to test TF graphs that accept parameters of any machine type (even int64 and float64), which are previously problematic due to the complexity of C calling conventions.

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.

The InterpreterAssembler needs to specify a specific CallDescriptor type
instead of using the SimplifiedCDescriptor type. This CL makes it possible
to specify the CallDescriptor used by the RawMachineAssembler instead of
specifying a MachineSignature.
Also removes instruction-selector-tester.h which was erroneously resurrected
at some point.

The RawMachineAssembler will be used to build the interpreter, so it needs
to move back to src/compiler.

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.

Along the way:
- Thread isolate parameter explicitly through code that used to
rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
affected code
- Change Hydrogen New<> instruction templates to automatically
pass isolate

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.
