Omnibus removal of register declarations
This removes most register declarations in C code (and accompanying
documentation) in the Perl core. Retained are those in the ext
directory, Configure, and those that are associated with assembly
language.
See:
http://stackoverflow.com/questions/314994/whats-a-good-example-of-register-variable-usage-in-c
which says, in part:
There is no good example of register usage when using modern compilers
(read: last 10+ years) because it almost never does any good and can do
some bad. When you use register, you are telling the compiler "I know
how to optimize my code better than you do" which is almost never the
case. One of three things can happen when you use register:
The compiler ignores it, this is most likely. In this case the only
harm is that you cannot take the address of the variable in the
code.
The compiler honors your request and as a result the code runs slower.
The compiler honors your request and the code runs faster, this is the least likely scenario.
Even if one compiler produces better code when you use register, there
is no reason to believe another will do the same. If you have some
critical code that the compiler is not optimizing well enough your best
bet is probably to use assembler for that part anyway but of course do
the appropriate profiling to verify the generated code is really a
problem first.

takes the portions that are identical and makes a common function out of
them, so the synchronization becomes automatic.

regcomp.c: Make sure counter same in passes 1 and 2
The number of elements was not being incremented in pass 1, whereas that
number is needed later on in pass 1. This did not cause a
bug, as currently, in pass 1 we care only if the count is 1 or not, and
this occurred only in a case where it would get incremented properly to
more than 1 anyway. But this is a potential bug that should be
squelched before it happens.

regcomp.c: Comments only
The diffs will show more than this, as a block of comments was moved and
revised

regcomp.c: Use old paradigm in dealing with flags recursively
In a recursive call to reg(), instead of passing our flags pointer, pass
a new one and upon return or in that result with the existing one. I
can see why this should be done, as you don't want to lose what you
already have, as reg() will start by resetting it to 0. I don't know
why one ands it with the known flags, but I'm presuming there is a
reason, and so am copying the paradigm. I searched the commit messages
and didn't find anything. No tests failed, and I didn't figure out a
test that would fail.

regcomp.c: Create NOTHING node when would have been 0 length EXACT
It's peculiar circumstances indeed that would get to this point in the
code with an EXACT node to be created, but nothing to populate it with.
Perhaps it is impossible; I'm not sure. But commit
5f820f894e71b6970a5aa0fd763a84b647fd628a changed the behavior, which I
discovered in later re-reading the code. Probably the node would be
populated with a single NUL. Just in case it is possible to get here
under these peculiar circumstances, this commit adds code to handle the
case, with a NOTHING node instead of a 0 length EXACT.

regcomp.c: Set flags when optimizing a [char class]
A bracketed character class containing a single Latin1-range character
has long been optimized into an EXACT node. Also, flags are set to
include SIMPLE. However, EXACT nodes containing code points that are
different when encoded under UTF-8 versus not UTF-8 should not be marked
simple.
To fix this, the address of the flags parameter is now passed to
regclass(), the function that parses bracketed character classes, which
now sets it appropriately. The unconditional setting of SIMPLE that was
always done in the code after calling regclass() has been removed.
In addition, the setting of the flags for EXACT nodes has been pushed
into the common function that populates them.
regclass() will also now increment the naughtiness count if optimized to
a node that normally does that. I do not understand this heuristic
behavior very well, and could not come up with a test case for it;
experimentation revealed that there are no test cases in our test suite
for which naughtiness makes any difference at all.

regcomp.c: change pattern to utf8 if needed in \N{}
This patch is in preparation for future patches that will no longer
always make any pattern that contains \N{} be encoded in UTF-8. Thus
this patch doesn't actually change anything, but enables future ones.
