If you just cast those patterns to float or double and pass them
around, the quiet/signaling NaN bit might change. We had several bugs
around this, so add these patterns to the general input vectors.

This oncovers a bug in the wasm interpreter, which will be fixed in a
separate CL.

Use the (D)CHECK_{EQ,NE,GT,...} macros instead of (D)CHECK with an
embedded comparison. This gives better error messages and also does the
right comparison for signed/unsigned mismatches.

This will allow us to reenable the readability/check cpplint check.

Because the toboolean operator may lower to a builtin call (which is
effectful in turbofan parlance after effect control linearization),
it really should be encoded as a simplified operator, which can
be optimized with respect for the effect chain in linearization.

No new functionality here, rather a furniture rearrangement in
the TurboFan node structure.

This addresses the odd performance cliff, where the CallIC tracks known
JSFunction targets, but goes MEGAMORPHIC when it sees a JSBoundFunction
target. With this fix in place the micro-benchmark on the bug goes from

  arrowCall: 82 ms.
  boundCall: 234 ms.

to

  arrowCall: 81 ms.
  boundCall: 80 ms.

so Function#bind doesn't cause any additional overhead anymore.

So far the JSCallReducer was only able to unfold constant
JSBoundFunction targets for JSCall nodes, which is not the
common case. With the introduction of JSCreateBoundFunction
operator earlier, we can now also recognize calls to bound
functions where the bind happens earlier in the function,
i.e. as the example of

  a.map(f.bind(self))

in https://twitter.com/BenLesh/status/920700003974123520, which
is a handy way to use Function#bind. So this transformation
takes a node like

  JSCall(JSCreateBoundFunction(bound_target_function,
                               bound_this,
                               a1,...,aN),
         receiver, p1,...,pM)

and turns that into

  JSCall(bound_target_function, bound_this, a1,...,aN,p1,...,pM)

allowing TurboFan to further inline the bound_target_function
at this call site if that's also inlinable (i.e. it's a known
constant JSFunction or the result of a JSCreateClosure call).

This improves the micro-benchmark from

  arrowCall: 55 ms.
  boundCall: 221 ms.
  arrowMap: 181 ms.
  boundMap: 806 ms.

to

  arrowCall: 71 ms.
  boundCall: 76 ms.
  arrowMap: 188 ms.
  boundMap: 186 ms.

so that Function#bind in this case is as fast as using closures,
which is an up to 4.3x improvement in the Array#map example.

This makes the function constexpr and implements it for arbitrary
unsigned integer types (up to 64 bits, but this can be extended if
needed).

Since we don't support gcc 2.96-4.0 any more, we can generalize the
V8_INFINITY macro to always use std::numeric_limits<double>::infinity().
This also makes value constexpr on all systems.

A followup CL will move feedback slot allocation to the bytecode generator,
which means it won't be done for asm_wasm code and the function will have an
incorrect vector spec. Since asm_wasm doesn't use a feedback vector, just
prevent it from being allocated for this code.
