Paul Clarke 4a1a0f6613 Add headers for new examples 
In the absence of sufficient context, the new examples added to:
- vec_double{e,h,l,o}
- vec_permxor
- vec_pmsum_be
- vec_slv
- vec_srv
- vec_sum2s
- vec_sum4s
- vec_sums
- vec_unsigned{e,o}
may appear to be strictly big-endian.

Add headers to these examples showing the element indicies,
which hopefully provides sufficient context.

Fixes #44.

Move the table so that it won't have a head-scratching location

functions.

as inputs should also be `vector signed char`.

Paul Clarke ace0e99214 Add example for vec_permxor 
`vec_permxor` is complex enough to warrant an example.

The table used is very wide. I squeezed it more by changing the names
of `index1` and `index2` to `x` and `y`, respectively.

Note: The table may still be too wide, as some additional warnings are
now generated during `mvn generate-sources`:
```
WARNING: Line 1 of a paragraph overflows the available area by more than 50 points. (See position 1:-1)

Paul Clarke 3d79fb03c1 Add examples to vec_vslv and vec_vsrv 
vec_vslv and vec_vsrv are confusing in their own right and even more
so because they operate only with big-endian semantics.

Some examples are warranted.

Note that the respective examples are arranged such that the impact of
shifting in zero bits has a visible impact.
