Bill Schmidt d939b73aac Move the endian-sensitive built-in function table 
Move the table so that it won't have a head-scratching location
in the HTML view.  Update it to add the first_match* and first_mismatch*
functions.

Fixed #39.

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)
Apr 30, 2020 8:44:03 PM org.apache.fop.events.LoggingEventListener processEvent
WARNING: Line 1 of a paragraph overflows the available area by 468 millipoints. (See position 14259:-1)
Apr 30, 2020 8:44:03 PM org.apache.fop.events.LoggingEventListener processEvent
...
WARNING: span="inherit" on fo:block, but no explicit value found on the parent FO.
```

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.

Paul Clarke 513de17330 Fix "Vector Registers as Part of VSRs" figure scaling 
The "Vector Registers as Part of VSRs" figure was very large,
especially as it immediately follows an almost identical figure.

Before this change:
fig-fpr-vsr.png: PNG image data, 663 x 300...
fig-vr-vsr.png:  PNG image data, 1367 x 608...

After this change:
fig-fpr-vsr.png: PNG image data, 663 x 300...
fig-vr-vsr.png:  PNG image data, 645 x 287...

I chose this size because the actual side boundaries of the
table most closely match in size.

The scaling, using The GIMP, resulted in somewhat blurry lines,
but still quite clear enough, and good enough.
