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

This makes us able to get rid of dependencies to parser.h from places
which only need the ParseInfo, and also gets rid of the curious Parser
<-> Compiler circular dependency.
Also IWYUd where necessary.

This also gets rid of the pending_error_handler field on DeclarationScope which wasn't actually used.

This reduces peak zone memory usage by ~10% on codeload and ~5% on mandreel.

The parser should never need to look at the underlying closure object,
hence the field can be moved from ParseInfo into CompilationInfo.

Moves all files related to AST and scopes into ast/,
and all files related to scanner & parser to parsing/.
Also eliminates a couple of spurious dependencies.

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.

This enables linter checking for "readability/namespace" violations
during presubmit and instead marks the few known exceptions that we
allow explicitly.

Rationale: separate the inputs and outputs of parsing + analysis from the business of compiling (i.e. generating machine code).

Parser must be able to operate independent of Isolate and the V8 heap during
parsing. After the heap-independent phase, there is a heap dependent phase,
during which we internalize strings, handle errors, etc.
This makes Isolate (also via CompilationInfo) unaccessible during parsing, and
thus decreases the probability of accidental code changes which would add
heap-dependent operations into the heap-independent phase.
Since Isolate is also accessible via CompilationInfo, now CompilationInfo is
only passed to the entry points of parsing, and not stored in Parser.

This analysis computes the set of variables that are assigned in each loop. This is useful to avoid creating redundant loop phis when building an SSA graph, which just waste memory and require analysis to get rid of.
This CL implements an AST walk for the analysis and plugs the result into the TurboFan graph builder. I left this analysis under a flag for A/B testing and until sufficient unit tests can be developed.
