837c91e87b [base] Template MatchFun in TemplateHashMapImpl
Make MatchFun a template parameter in TemplateHashMapImpl, moving the
PointersMatch function down to an implementation which extends
TemplateHashMapImpl to void* key and value (i.e. the same as the current
HashMap and ZoneHashMap typedefs).

This will allow other instantiations of TemplateHashMapImpl, with
different MatchFun values, e.g. std::equal_to, to have their key
equality test inlined, rather than calling a function pointer,

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

2fd55667a6 Move hashmap into src/base.
We ported hashmap.h into libsampler as a workaround before, so the main focus of
this patch is to reduce code duplication. This patch moves the hashmap into
src/base as well as creates DefaultAllocationPolicy using malloc and free.

cb7aa79b12 Expose a lower bound of malloc'd memory via heap statistics
We expect that the majority of malloc'd memory held by V8 is allocated
in Zone objects. Introduce an Allocator class that is used by Zones to
manage memory, and allows for querying the current usage.

47502a238b [runtime] Replace global object link with native context link in all contexts.
Previously all contexts had a link to the global object, but what is
required in most cases (except for the global load, store and delete
case) is the native context.

This also removes the second dummy global object that was still linked
to every native context. We will add a different mechanism to ensure
that builtins do not pollute the actual global object during
bootstrapping.

Drive-by-fix: Unify some MacroAssembler magic and drop obsolete stuff.

00a07bc1b7 Remove inline header includes from non-inline headers (1).
This tries to remove includes of "-inl.h" headers from normal ".h"
headers, thereby reducing the chance of any cyclic dependencies and
decreasing the average size of our compilation units.

Note that this change still leaves 7 violations of that rule in the
code. However there now is the "tools/check-inline-includes.sh" tool
detecting such violations.

This is a mostly mechanical CL (more than 90% Emacs macros and

OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and

cd5ea74700 Replace 'operator*' with explicit 'get' method on SmartPointer
Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.

Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.

Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.

drive-by: fixed use after free in src/factory.cc

e76482f2da Cleanup Mutex and related classes.
Drop the previous Mutex and ScopedLock classes from platform files.

Add new Mutex, RecursiveMutex and LockGuard classes, which are
designed after their C++11 counterparts, so that at some point
we can simply drop our custom code and switch to the C++11
classes. We distinguish regular and recursive mutexes, as the
latter don't work well with condition variables, which will be
introduced by a followup CL.
