Summary: The MSA ld.[bhwd] and st.[bhwd] instructions scale the immediate by the element size before use as an offset. The offset must therefore be a multiple of the element size to be valid in these instructions. However, an unaligned base address is valid in MSA. This commit causes the compiler to emit valid code when the calculated offset is not a multiple of the element size by accounting for the offset using addiu and using a zero offset in the load/store.
