Ryan Macnak a144e263ce Allocate from the root VMAR on Fuchsia.
Removes the need for the VmarList.

Overallocate VMOs instead of VMARs to get aligned memory.

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 1393e84863 [Fuchsia] Give VMOs names
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".

Ryan Macnak 877284947b Rename TARGET_OS_* to HOST_OS_*.
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.
