llvm-6502/test/CodeGen/X86/2009-03-07-FPConstSelect.ll
Chris Lattner 600fec3cea reapply my previous patch (r66358) with a tweak to set the
alignment of the generated constant pool entry to the
desired alignment of a type.  If we don't do this, we end up
trying to do movsd from 4-byte alignment memory.  This fixes
450.soplex and 456.hmmer.
