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.
Change occurrences of "An example follows" to
"An example for input _i_ of type _t_ follows",
in cases where an intrinsic has more than one possible input type.

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.

- 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.

Since there isn't a straightforward way of initializing `__int128` type
variables, provide an example for initializing `vector __int128` here.

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.

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.
