Strictly speaking there are some left in api.cc, but they are in
deprecated functions with non-deprecated alternatives.
Apart from changes made using tooling, this also modifies
FieldType::AsClass to return Map* rather than Handle<Map> and converts
its call sites to create the Handle when they need it - currently
several sites immediately dereference the Handle.
Also marks WasmDebugInfo as NeverReadOnlySpaceObject so GetIsolate and
GetHeap remain usable.

Downside: this adds all kinds of weird includes in the .cc files.

This reverts commit 7db0ecdec3.
Manual revert since automatic revert is too large for the web interface.

Our Type class has a semantic and representational dimension.
Much code in src/ast, Crankshaft and Turbofan is based on it.
Going forward in Turbofan we'd like to remove representational information
entirely. To that end, new type AstType has been created to preserve
existing behavior for the benefit of Crankshaft and the AST.

When FieldType::None() returns a cast Smi::FromInt(0), which translates
as nullptr, the FieldType::IsNone() check becomes equivalent to
`this == nullptr` which is not allowed by the standard and
therefore optimized away as a false constant by GCC 6.
This has lead to crashes when invoking methods on FieldType::None().
Using a different Smi constant for FieldType::None() makes the compiler
always include a comparison against that value. The choice of these
constants has no effect as they are effectively arbitrary.

If the intersection of the types of nodes a and b is empty, then there's
no way that a and b could ever refer to the same object, so we can use
that information for alias analysis.
Drive-by-fix: Improve use of types to enable typed alias analysis to
become more effective. Also fix an ASAN issue uncovered by this CL.
