Log:
Add a VEC_DUPLICATE_EXPR tree code and associated optab

This patch adds a tree equivalent of the existing rtl
VEC_DUPLICATE code.  It also adds a new optab for expanding
VEC_DUPLICATE_EXPR statements.

The code is treated as a GIMPLE_SINGLE_RHS rather than a
GIMPLE_UNARY_RHS.  This is so that we can treat constant
vector duplicates as gimple values, like a VECTOR_CST would be.

The patch also adds a missing @tindex for VEC_COND_EXPR.
