incremental patch

This fixed matmul_i2.c, DR_BASE_ADDRESS wasn't in this case TYPE_RESTRICT, nor
SSA_NAME, but POINTER_PLUS_EXPR, yet in the end was based on a restrict
pointer.
Unfortunately other matmul*.c stuff in libgfortran is still broken.  I'm
wondering if the strict alias checking introduced in r140781 isn't too eager
when restricted pointers are used...
