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.

Split directory_posix -> directory_(android|linux|macos)
This allows us to cleanly make Android-specific changes to
directory_android.cc
Copy all _linux files to _android files and edit as needed to account
for the differences between Linux and Android:
+ getcwd(0, NULL) doesn't work on Android, have to emulate
+ Android doesn't have a '/tmp' directory, have to emulate
+ Android doesn't provide mkdtemp(), have to emulate.
+ Small differences in the available system include files.
+ Use pthread_cond_timedwait_monotonic instead of
pthread_condattr_setclock
