[LLVMdev] Why does x86 fast-isel reject unaligned stores?

[Jim Stichnoth]

In X86FastISel::X86SelectStore(), improperly aligned stores are rejected
and handled by the DAG-based ISel.  However, X86FastISel::X86SelectLoad()
makes no such requirement.  Is there a reason for this alignment
restriction on stores?  Would it be reasonable to remove it?
