VE used to allocate VM1, VM2, VMP2 (VM4+VM5), and VM3. This patch
corrects to allocate VM1, VM2, VMP2 (VM4+VM5), and VM6. Also add
a regression test.

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.

This defines a 'fastcc' for the VE target and implements vreg-to-vreg
copy for parameter passing. The 'fastcc' extends the standard CC for
SX-Aurora with register passing of vector-typed parameters and return
values.

Prepare for supporting different calling conventions by factoring out
things into CC-dependent selection functions (getParamCC, getReturnCC).

Support f128 using VE instructions. Update regression tests.
I've noticed there is no load or store i128 test, so I add them too.
