i386.c (TARGET_VECTORIZE_BUILTIN_CONVERSION): Define. 

        * config/i386/i386.c (TARGET_VECTORIZE_BUILTIN_CONVERSION): Define.
        (ix86_builtin_conversion): New function.

testsuite/ChangeLog:

        * gcc.dg/vect/vect-intfloat-conversion-1.c: Loop gets vectorized
        on i?86 and x86_64.
        * gcc.dg/vect/vect-intfloat-conversion-2.c: Ditto.
        * gcc.dg/vect/vect-floatint-conversion-1.c: New.
        * gcc.dg/vect/vect-93.c: Another loop gets vectorized
        on i?86 and x86_64.
        * gcc.dg/vect/vect-113.c: Ditto.
