Thanks for feedback. It turns out that the vmrgew and vmrgow instructions
require power 8.
After coordinating with Segher on minor refinements to the test cases, I have
committed the patch as quoted below to the trunk.

This patch fixes an error in the code generation for vec_pack (vector double,
vector double). As previously implemented, this built-in function translates
to the vpkudum instruction.
This patch causes vec_pack (vector double, vector double) to behave the same as
vec_float2 for the same type
