        * config/i386/i386.h (enum ix86_stack_slot): Add SLOT_VIRTUAL.
        * config/i386/i386.c (assign_386_stack_local): Assert that
        SLOT_VIRTUAL is valid only before virtual regs are instantiated.
        (ix86_expand_builtin) [IX86_BUILTIN_LDMXCSR, IX86_BUILTIN_STMXCSR]:
        Use SLOT_VIRTUAL stack slot instead of SLOT_TEMP.
        * config/i386/i386.md (truncdfsf2, truncxf<mode>2): Ditto.
