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,

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.
