radeon/llvm: Move SMRD IMM pattern before SMRD SGPR pattern 

In tablegen, if two patterns match, the one that comes first in the file
is given preference.  We want the SMRD IMM pattern to be given
preference, because it encodes the pointer offset in its immediate
field, which saves us an add instruction.
