This adds new rules to recognize consecutive byte loads and stores and lowers them to loads and stores such as lhz, lwz, ld, sth, stw, std. This change only covers the little endian cases on little endian machines, such as is found in encoding/binary UintXX or PutUintXX for little endian. Big endian will be done later. Updates were also made to binary_test.go to allow the benchmark for Uint and PutUint to actually use those functions because the way they were written, those functions were being optimized out. Testcases were also added to cmd/compile/internal/gc/asm_test.go.
