In section "Vector Function Name Mangling", I'm afraid we can't leave the <isa>
with an entry as generic as VSX.
There are VSX instructions included in ISA 3.0 that will not execute in ISA
2.07. So, I think we need 2 <isa> entries there:
1. ISA 2.07, which is the minimum ISA required in this document.
2. ISA 3.0
