Bill Schmidt 8c875503ea Merge branch 'v2'
The v2 branch was used to work on PVIPR v2.0 while PVIPR v1.0 was
still under review.  Since PVIPR 1.0 has now been published, and a
separate document will be used for v1.0 errata, merge v2 into mainline
and use mainline for further updates.

Paul Clarke 0d686a2a8f Add examples for "match" intrinsics
Add examples for
- `vec_first_match_index`
- `vec_first_match_index_or_eos`
- `vec_first_mismatch_index`
- `vec_first_mismatch_index_or_eos`

Also, `vec_first_match_index` implmentations in this document and
in GCC were behaving like `vec_first_match_or_eos_index`.
Correct this document.  GCC PR94833 was already opened.

Fixes #18.

Paul Clarke c78c224df0 Clarify content regarding operators
- Explicitly mention that there are no default conversions.
- Clarify that binary operations are on like types.
- Clarify requirements for the ternary operator and add an example.

Asserting that the clarified content is clear enough,
Fixes #11.

Paul Clarke a87ff8bd02 Add example initializer for vector __int128

variables, provide an example for initializing `vector __int128` here.

Paul Clarke 8ca90e8fd6 Add example for vec_bperm
vec_bperm is a challenge for showing an example using just tables,
but I've made an attempt.

Three tables are used:
- The values of the input vectors *a* and *b*.
- A zoomed in view of the last two bytes of *a* and the bit
  manipulations therein that leads to the intermediate result.
- The result vector *r*.

Only one example has been provided, but it's getting big.

Fixes #14.

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.
