Suppress some Solaris warnings
We get an integer overflow message when we left shift a 1 into the
highest bit of a word. This changes the 1's into 1U's to indicate
unsigned. This is done for all the flag bits in the affected word, as
they could get reorderd by someone in the future, unintentionally
reintroducing this problem again.

B/Makefile.PL: Allow constants to be long/unsigned
This looks for numerical constants, but failed to see long and/or

Deprecate multiple "x" in "/xx"
It is planned for a future Perl release to have /xx mean something
different from just /x. To prepare for this, this commit raises a
deprecation warning if someone currently has this usage. A grep of CPAN
did not turn up any instances of this, but this is to be safe anyway.
The added code is more general than actually needed, in case we want to
do this for another flag.

op_reg_common.h: #define in terms of more basic one
The mask to copy bits should always include at least the compile-time
bits. By defining it in terms of the compile-time bits, we make it
easier to change and understand.

Up regex flags limit for (??{})
Previously the regex pattern compilation flags needed for this construct
would fit into an 8-bit byte. This conveniently fits into the flags
structure element of a regnode. There are changes coming that require
more than 8 bits, so in preparation, this commit adds an argument to the
node that implements (??{}) (31-bits usable for flags), and moves the
storage to that.

constant.

This adds a function to allocate a regnode with 2 32-bit arguments, and
uses it, rather than the ad-hoc code that did the same thing previously.
This is in preparation for this code being used in a 2nd place in a
future commit.

regcomp.c: Extract duplicated code to fcn
This causes the nearly-duplicate code of S_reg_node and S_reganode to be
placed into a single function, S_regnode_guts.
There is one place where it might not be obvious that this doesn't
change things. And that is under DEBUGGING, reg_node() called
Set_Node_Offset(RExC_emit, RExC_parse + (op == END));
and reganode called
Set_Cur_Node_Offset;
However Set_Cur_Node_Offset is defined to be
Set_Node_Offset(RExC_emit, RExC_parse)
and since op will never be END for reganode, the two statements are
equivalent.

regcomp.c: Move some statements
These statements are moved to after the debugging code so that the two
functions are essentially identical before them. This will allow the
two to be combined in a future commit. I verified by testing that the
debugging info was not affected.

op.h: Move flag bits; comment shared-bit scheme
This changes op.h to correspond with regexp.h. It moves all the used
bits up in the word so that if a new shared bit is added, the #error
will be triggered, alerting the person doing it that things need
adjusting so binary compatibility is preserved.

bits at either end can be added without having to adjust many other
defines.

regexp.h: Define flag bit directly, not indirectly
This #defined a symbol then did a compile time check that it was the
same as another symbol. This commit simply defines it as the other
symbol directly, and moves it to above the other definitions, which it
no longer is part of. This prepares for the next commit.

regexp.h Remove unused bit placeholders
We do not need a placeholder for unused flag bits. And removing them
makes the generated regnodes.h more accurate as to what bits are
available.

commit afe4da9ddf30127ee8f34fe692e650c99bdf2b8c
Author: Karl Williamson <[email protected]>

regexp.h: Move regex flag bit positions.
This moves three bits to create a block of unused bits at the beginning.
The first bit had to be moved to make space for other uses that are
coming in future commits. This breaks binary compatibility, so might as
well move the other two bits so that all the unused bits are
consolidated at the beginning.
This pool of unused bits is the boundary between the bits that are
common to op.h and regexp.h (and in op_reg_common.h) and those that are
separate. It's best to have all the unused bits there, so when we need
to use one, it can be taken from either side, as needed, without us
being trapped into having an available bit, but of the wrong kind.
