Hello!
We have to check natural alignment of the operand in
misaligned_operand predicate. This predicate is used to check SSE
memory operands for alignment, when movaps instead of movups can be
used. This change makes predicate independent of BIGGEST_ALIGNMENT
setting.

* config/i386/predicates.md (misaligned_operand): Return true if
operand is aligned to less than its natural alignmnet.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32},
committed to mainline SVN.
Uros.
