utf8.c: Move most important conditional to be first
It turns out that the information generated in this block is only needed
if the final conditional in this complicated group of them is true,
which checks if the caller wants anything special for certain classes of
code points. Because that final condition is subsidiary, the block was
getting executed just to be thrown away.

utf8.c: Split conditionals
As a first step in simplifying this overly complicated series of
conditionals, pull out the first one into a separate 'if'. The next
commits will do more.

utf8.c: Further simplify a complex conditional
This hoists a clause in a complex conditional to the 'if' statement
above it, converting that to two conditionals from one, while decreasing
the number in the much larger interior 'if' by 1.
This is in preparation for further simplifications in the next few
commits.

utf8.c: Check specially for perl-extended UTF-8
More rigorous testing of the overlong malformation, yet to be committed,
showed that this needs to be handled specially. This commit does part
of that.
Perl extended UTF-8 means you are using a start byte not recognized by
any UTF-8 standard. Suppose it is an overlong sequence that reduces
down to something representable using standard UTF-8. The string still
used non-standard UTF-8 to get there, so should still be called out when
the input parameters to this function ask for that. This commit is a
first step towards that.

utf8.c: Remove intermediate value
By not overriding the computed value of malformed input until later in
the function, we can eliminate this temporary variable. This paves the
way to a much bigger simplification in the next commit.

utf8.c: Combine two blocks
It turns out that the work being done in the first block is only used in
the second block. If that block doesn't get executed, the first block's
effort is thrown away. So fold the first block into the second. This
results in a bunch of temporaries that were used to communicate between
the blocks being able to be removed.
More detailed comments are added.

Admittedly not much work, but I realized in code reading that there
are function exits that ignore this initialization. Instead
move the initialization to later, where it is actually needed

utf8n_to_uvchr_msgs_helper(): Refactor expression
More rigorous testing of the overlong malformation, yet to be committed,
showed that this didn't work as intended.
The IS_UTF8_START_BYTE() excludes start bytes that always lead to overlong
sequences. Fortunately the logic caused that to be mostly bypassed. But this
commit fixes it all.
