Ryan Macnak b247090c9e [vm] Align old-space pages.
Allows quick access to the page header for any old-space object, which is a convenient place to keep forwarding information.

Also combine the reserve and commit operations of VirtualMemory.

Zachary Anderson 103881d01c Make header include guards great again
i.e. #ifndef VM_WHATEVER -> #ifndef RUNTIME_VM_WHATEVER

This lets us remove a hack from the PRESUBMIT.py script that existed
for reasons that are no longer valid, and sets us up to add some
presubmit checks for the GN build.

koda@google.com bd1c7ca854 Make unused semispace available to other isolates.
When not scavenging, hand the unused semispace back to the system,
with a one-element cache (to avoid the cost of clearing).

Example memory footprint reduction:
* a short-running single-isolate process that never needs a scavenge: half
* VM service enabled but never used: one semi-space
* N isolates with no more than M scavenging simultaneously: N-M semi-spaces

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.
