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.

Correct a small bug which throws a compile-time assertion for ARMv8
builds since this change:

This does not add full support for ARMv8 instructions; it simply sets
the CAN_USE_ARMV7_INSTRUCTIONS define on ARMv8 builds.

For asm.js we now have a dedicated AsmTyper, that uses it's own type
system (which is tailored towards asm.js), and so we don't need the
special asm.js types anymore in the TypeCache. This also moves the
TypeCache into the src/compiler directory, because it doesn't make
sense to use outside anyways.

Significantly tanks parsing. We probably should just keep on doing what we're doing: partially deserialize while resolving variables. If we do scope-info backed resolution after regular resolution based on remaining free variables, we can probably reduce the time-frame of that part. We soon after anyway need to sync with the main thread.

Introduce a new TypedOptimization reducer that contains the type
based optimization reduction steps, which are not (directly)
related to lowering JavaScript operators based on types (which is
what JSTypedLowering is supposed to do).
This also addresses a chicken-and-egg problem that we see in the
Octane/Mandreel benchmark where type based constant folding isn't
applied to the numeric comparison operators introduced by the
JSTypedLowering itself, and thus gives up to 10% speedup for the
benchmark.

When doing a component build, some test binaries link against the object
files directly, bypassing the components. This results, however, and
rightly so, in linker warnings. In gyp, we just suppressed them. During
the transition to gn, this was dropped for two binaries.
Here I add the suppressions back in.
Long term, we should either change the tests to go through the public
API, or export the required symbols.

This patch parametrizes AstTraversalVisitor by the actual subclass,
in a similar way as AstVisitor is parametrized. This allows a
subclass to, e.g., override the Visit method and still use the
traversal mechanism. It also allows the subclass to override the
specific visiting methods, without them being virtual.
This patch also removes AstExpressionVisitor, subsuming its
functionality in AstTraversalVisitor.
