Simon Moll b955c7e630 [VE] VE Vector Predicated SDNode, vector add isel and tests
VE Vector Predicated (VVP) SDNodes form an intermediate layer between VE
vector instructions and the initial SDNodes.

We introduce 'vvp_add' with isel and tests as the first of these VVP
nodes. VVP nodes have a mask and explicit vector length operand, which
we will make proper use of later.

Simon Moll ffe6c97f6b [VE] VEC_BROADCAST, lowering and isel
This defines the vec_broadcast SDNode along with lowering and isel code.
We also remove unused type mappings for the vector register classes (all vector MVTs that are not used in the ISA go).

We will implement support for short vectors later by intercepting nodes with illegal vector EVTs before LLVM has had a chance to widen them.
