dalvik/vm: Dalvik startup with a low memory footprint

Initialize concurrentStartBytes and createMspace using HEAP_MIN_FREE.
This helps save Android framework memory after boot.

This is for low memory targets only(<=512MB RAM & hdpi resolution)
Also, set TARGET_ARCH_LOWMEM in the BoardConfig.mk file of a device
for this patch to take effect.

dalvik: use T3 branch when target offset is too large

T1 branch has offset limit of [-256, 254]. T3 branch has offset
limit of [-1048576, 1048574]. Use T3 branch when target offset
falls outside T1 range to avoid compiliation abort.
