    x86: Fix ix86_expand_vector_init for V*TImode [PR100887]

    We have vec_initv4tiv2ti and vec_initv2titi patterns which call
    ix86_expand_vector_init and assume it works for those modes.  For the
    case of construction from two half-sized vectors, the code assumes it
    will always succeed, but we have only insn patterns with SImode and DIm=
ode
    element types.  QImode and HImode element types are already handled
    by performing it with same sized vectors with SImode elements and the
    following patch extends that to V*TImode vectors.

            * config/i386/i386.c (ix86_expand_vector_init): Handle
            concatenation from half-sized modes with TImode elements.
