Ben Shi 2a6e39dbf8 [AVR] Do not emit 'LPM Rd, Z' on devices without FeatureLPMX 
The 'LPM' instruction has three forms:

------------------------
| form       | feature |
| ---------- | --------|
| LPM        | hasLPM  |
| LPM Rd, Z  | hasLPMX |
| LPM Rd, Z+ | hasLPMX |
------------------------

The second form is always selected in ISelDAGToDAG, even on devices
without FeatureLPMX. This patch emits "LPM + MOV" on devices with
only FeatureLPM.
