i965: Fix src0 vs src1 typo
A typo caused us to copy src0's reg file to src1 rather than reading
src1's as intended. This caused us to fail to compact instructions like
mov(8) g4<1>D 0D { align1 1Q };
because src1 was set to immediate rather than architecture file. Fixing
this reenables compaction (after the precompact() pass changes the data
types):
mov(8) g4<1>UD 0x00000000UD { align1 1Q compacted };
