Please see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27971

Modified find_split_point in combine.c to catch an rtx of the form:

(mem/s:SI (plus:SI (and:SI (reg/v:SI 59 [ x ])
               (const_int 12 [0xc]))
           (symbol_ref:SI ("array") <var_decl 0xf7ef20b0 array>)) [3
array S4 A32])

and introduce a split at the first operand of the PLUS expr.

I cannot approve it, but it seems ok apart from the lack of a testcase.
