[PATCH] [mips][microMIPS] Implement LWSP and SWSP instructions

[Sasa Stankovic]

This patch doesn't correctly handle the case when (offset % 4) != 0. For example, for the following instruction

lw    v1,123(sp)

instead of emitting 32-bit "lw    v1,123(sp)" the patch emits 16-bit "lw    v1,120(sp)"

Please include this instruction in the tests.
