This CL assigns names to vmos formatted as "isolate space type" where
isolate is the name of the isolate, space is "oldspace" or "newspace",
and type is "code" or "data".

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

Change executable pages to be read/execute but not writable by default.
All pages are made temporarily writable just before a full GC, because both
the mark and sweep phases write to the pages. When allocating in a page and
when patching code, the pages are made temporarily writable.
The order of allocation of Code and Instructions objects is changed so that
a GC will not occur after Instructions is allocated. (A full GC would
render the Instructions unwritable.) A scoped object is used to make memory
protection simpler.

I added a cc test that is expected to crash.

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.
