Improve reading ADC result
7.3.0-atmel3.6.1-arduino7 gcc fails to optimize separate reading from ADCL and ADCH. It produces additionally three eor commands or in some cases two mov commands in the assembly code (see discussion #344). These commands swap register contents before store them to data area. So they are completely unnecessary. Reading ADC result with ADC macro fixes it and gcc generates the right code..
