The CBR instruction is just an ANDI instruction with the immediate
complemented.
Because of this, prior to this change TableGen would warn due to a
decoding conflict.
This commit fixes the existing compilation warning:
===============
[423/492] Building AVRGenDisassemblerTables.inc...
Decoding Conflict:
0111............
01..............
................
ANDIRdK 0111____________
CBRRdK 0111____________
================
After this commit, there are no more decoding conflicts in the AVR
backend's instruction definitions.
Thanks to Eli F for pointing me torward `t2_so_imm_not` as an example of
how to perform a complement in an instruction alias.
Fixes BugZilla PR38802.
