Log:
Add a VEC_SERIES rtl code

This patch adds an rtl representation of a vector linear series
of the form:

  a[I] = BASE + I * STEP

Like vec_duplicate, the new rtx can be used for both constant
and non-constant vectors.  When used for constant vectors it
is wrapped in a (const ...).  At the moment it is restricted
to integer elements, to avoid concerns over floating-point
rounding.
