Prevent folding of a node with multiple uses if the node already folds a load!

Here is an example where the load ended up being done twice:
%A = global uint 0

%tmp = load uint *%A;
%X = shl uint %tmp, ubyte %C
%Cv = sub ubyte 32, %C
%Y = shr uint %B, ubyte %Cv
%Z = or uint %Y, %X
store uint %Z, uint* %A
ret uint %Z
}

Use pattern information to determine whether the use expects this
...
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.
