Ryan Macnak b1c09ecd8f [vm] Make naming more consistent when converting between handles, tagged and untagged pointers.
Currently we have things called XPtr which are not what you get from ptr().

Old world:
handle->raw() returns RawObject* (tagged)
raw_obj->ptr() returns RawObject* (untagged)

After 6fe15f6df9:
handle->raw() returns ObjectPtr
obj_ptr->ptr() returns ObjectLayout*

New world:
handle->ptr() returns ObjectPtr
obj_ptr->untag() returns UntaggedObject*

Ryan Macnak 6fe15f6df9 [vm] Represent tagged pointers as C++ value types instead of C++ pointer types.
This works around bugs in UndefinedBehaviorSanitizer and Clang.

Liam Appelbe d49bf6f25a [vm] Remove misleading usings.
Patchset 1 contains just the usings I deleted (<100 lines). All the
other diffs in the rest of the CL are just fixing all the places that
were broken by this.

Vyacheslav Egorov 8a179fb953 [VM, Compiler] Move compiler to a separate folder.
New folder structure (nested under vm/):

- compiler/
-   jit/         - JIT specific code
-   aot/         - AOT specific code
-   backend/     - all middle-end and back-end code (IL, flow graph)
-   assembler/   - assemblers and disassemblers
-   frontend/    - front ends (AST -> IL, Kernel -> IL)

compiler/README.md would be the documentation root for the compiler
pipeline

asiva@google.com eaebf15f43 Fix for issue 14790 - Crash when using dartium devtools
The stack frame iteration during GC was missing one slot in stub frames that
did not save the pool pointer.

- This change makes all stub frames uniform, i.e they always save/restore the pool pointer. This ensures that we will traverse all slots on the stack.

- A new constant called kFirstObjectSlotFromFp has been added which is used as the slot to start stack traversal.

(The ARM and MIPs changes will be in a different CL)

zra@google.com df2054dae7 Sets a register aside on x64 for use as a pool-pointer. It is loaded and restored from the code object on Frame entry and exit. All LoadObject calls that can, and many calls and jumps through ExternalLabels now use the pool-pointer. The --compiler-stats flag when running dart2js indicates that code size is reduced ~13%, and more is probably possible.

sgjesse@google.com bf67f24098 Move assert.h/assert.cc from runtime/vm to runtime/platform
The purpose of this change is twofold:

1. Source in the bin directory can now use the same assertions as
   source in the vm directory. The ASSERT macro used by the code
   in runtime/bin was just defined to use assert from the standard
   C library.
2. Moving other implementation parts from runtime/vm to
   runtime/platform (e.g. classes Monitor and Mutex) for sharing
   between runtime/bin and runtime/vm will be easier as these
   implementations rely on these assertion macros.

Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.

All the code for asserts is still in the dart namespace.

Also re-arranged the order of includes to be alphabetically in
the files touched.
