JIT: Performance fix for const doubles

Some recent Arm processors take a performance hit when
creating a floating point double by loading it as a pair of singles.
Legacy code to support soft floating point doubles as a pair of core
registers loaded double immediates in this way.

With the CL, we handle double immediates as a single unit.

(cherry-pick of c8129911e598ad0ca8d7b31012444ab6ce8bce45.)

Use ALOGE rather than SLOGE for mountEmulatedStorage failures.

Otherwise the actual failure isn't in logcat, and all you see there
is the rather confusing:

  E dalvikvm: cannot mountExternalStorage(): Success

Zygote: Restrict slave mountspace so Dalvik apps can mount system-wide volumes

Android 4.2 implements multi-user storage using per-process mount
namespaces.  Originally, everything under "/" (the entire filesystem
hierarchy) is marked as a recursive-slave mountspace for all zygote
instances.  This is done so that user-storage sandbox mounts under
/storage/emulated are hidden from other apps and users.

Unfortunately this means that any Dalvik app (actually, any program whose
clone/fork ancestry includes a Dalvik zygote, which is everything except
services spawned directly from init) cannot mount system-wide volumes.
Thus, apps like CifsManager are effectively broken in Android 4.2, since
its cifs mounts are only visible to the CifsManager app itself.  All other
apps see empty mountpoints instead of the mounted volume.  Furthermore,
Linux provides no provision for a process to "escape" a recursive-slave
mountspace in versions prior to Linux 3.8 (setns syscall).

Here, we restrict the slave mountspace to /storage (and, due to a possible
kernel bug, /mnt/shell/emulated) so that Dalvik apps can mount system-wide
volumes elsewhere (with appropriate permission, as in earlier versions of
Android), while retaining full multi-user storage compatibility.

This change requires that a tmpfs volume is mounted as /storage in init.rc.
If this volume is unavailable, then Zygote falls back to the previous
behavior of marking the entire filesystem hierarchy as slave.  It also
implicitly requires that EMULATED_STORAGE_TARGET is path-prefixed by (part
of the subhierarchy of) ANDROID_STORAGE, which is the typical case.
