dalvik: rework 3 and 4-GB dalvik heap configurations
The previous configuration sets target utilization as .25, which is geared towards low memory devices. This path increases it to .75 and makes us pass the check: (heaptargetutilization / 2) * heapsize = heapgrowthlimit Example: heapgrowthlimit: 256m heapsize: 512m heaptargetutilization: 0.75 0.75/2 * 512 = 192 To pass the check this has to be true: 192 = 256 (WRONG) Check not passed. This new configuration is optimized for higher RAM devices and passes the check: heapgrowthlimit: 384m heapsize: 1024m heaptargetutilization: 0.75 0.75/2 * 1024 = 384 384 = 384 (TRUE) Check passed.
