    PR 19051: support of inferior call with gnu vector support on ARM

    This patch teaches GDB to support gnu vector in inferior calls.  As a
    result, fails in gdb.base/gnu_vector.exp are fixed.  The calling
    convention of gnu vector isn't documented in the AAPCS, because it
    is the GCC extension.  I checked the gcc/config/arm/arm.c, understand
    how GCC pass arguments and return values, and do the same in GDB side.

    The patch is tested with both hard float and soft float on arm-linux.
