[MERGE] only copy bits of regex match string
When making a copy of the string being matched against (so that $1, $&
et al continue to show the correct value even if the original string is
subsequently modified), only copy that substring of the original string
needed for the capture variables, rather than copying the whole string.
This is a big win for code like
$&;
$_ = 'x' x 1_000_000;
1 while /(.)/;
Also, when pessimizing if the code contains $`, $& or $', record
the presence of each variable separately, so that the determination of the
substring range is based on each variable separately. So performance-wise,
$&; /x/
is now roughly equivalent to
/(x)/
whereas previously it was like
/^(.*)(x)(.*)$/
and
$&; $'; /x/
is now roughly equivalent to
/(x)(.*)$/
etc.
Finally, this code (when not in the presence of $& etc)
$_ = 'x' x 1_000_000;
1 while /(.)/;
used to skip the buffer copy for performance reasons, but suffered from $1
etc changing if the original string changed. That's now been fixed too.

fix a bug in handling $+[0] and unicode
The code to decide what substring of a pattern target to copy for the
sake of $1, $& etc, would, in the absence of $&, only copy the minimum
range needed to cover $1,$2,...., which might be a shorter range than
what $& covers. This is fine most of the time, but, when calculating
$+[0] on a unicode string, it needs a copy of the whole part of the string
covered by $&, since it needs to convert the byte offest into a char
offset.
So to fix this, always copy as a minimum, the $& range.
I suppose we could be more clever about this: detect the presence
of @+ in the code, only do it for UTF8 etc; but this is simple

Don't copy all of the match string buffer
When a pattern matches, and that pattern contains captures (or $`, $&, $'
or /p are present), a copy is made of the whole original string, so
that $1 et al continue to hold the correct value even if the original
string is subsequently modified. This can have severe performance
penalties; for example, this code causes a 1Mb buffer to be allocated,
copied and freed a million times:
$&;
$x = 'x' x 1_000_000;
1 while $x =~ /(.)/g;
This commit changes this so that, where possible, only the needed
substring of the original string is copied: in the above case, only a
1-byte buffer is copied each time. Also, it now reuses or reallocs the
buffer, rather than freeing and mallocing each time.
Now that PL_sawampersand is a 3-bit flag indicating separately whether
$`, $& and $' have been seen, they each contribute only their own
individual penalty; which ones have been seen will limit the extent to
which we can avoid copying the whole buffer.
Note that the above code *without* the $& is not currently slow, but only
because the copying is artificially disabled to avoid the performance hit.
The next but one commit will remove that hack, meaning that it will still
be fast, but will now be correct in the presence of a modified original
string.
We achieve this by by adding suboffset and subcoffset fields to the
existing subbeg and sublen fields of a regex, to indicate how many bytes
and characters have been skipped from the logical start of the string till
the physical start of the buffer. To avoid copying stuff at the end, we
just reduce sublen. For example, in this:
"abcdefgh" =~ /(c)d/
subbeg points to a malloced buffer containing "c\0"; sublen == 1,
and suboffset == 2 (as does subcoffset).
while if $& has been seen,
subbeg points to a malloced buffer containing "cd\0"; sublen == 2,
and suboffset == 2.
If in addition $' has been seen, then
subbeg points to a malloced buffer containing "cdefgh\0"; sublen == 6,
and suboffset == 2.
The regex engine won't do this by default; there are two new flag bits,
REXEC_COPY_SKIP_PRE and REXEC_COPY_SKIP_POST, which in conjunction with
REXEC_COPY_STR, request that the engine skip the start or end of the
buffer (it will still copy in the presence of the relevant $`, $&, $',
/p).
Only pp_match has been enhanced to use these extra flags; substitution
can't easily benefit, since the usual action of s///g is to copy the
whole string first time round, then perform subsequent matching iterations
against the copy, without further copying. So you still need to copy most
of the buffer.

The documentation for ${^PREMATCH} etc states that it's only guaranteed to

Revert "toke.c: PL_in_eval purge"
This reverts commit
5c49e90fd624f3ab1cdb1f1d8e4f0525d7881b99.
This change broke line numbers under mad when the last statement in the main program lacks a semicolon.
I was mistaken in thinking that PL_rsfp would always be true when
PL_in_eval is false.
But the use of PL_in_eval is still wrong. Under a mad build, we get
this inconsistency in line numbers:
$ perl -e 'print "\n-e undef\n"' > foo
$ ./miniperl foo
Use of uninitialized value in -e at foo line 2.
$ ./miniperl -we 'require "foo"'
Use of uninitialized value in -e at foo line 3.
foo did not return a true value at -e line 1.

Fix two minor s//.../e parsing bugs
It may be an odd place to allow comments, but s//"" # hello/e has\
always worked, *unless* there happens to be a null before the first #.
scan_subst in toke.c wraps the replacement text in do { ... } when the
/e flag is present.
It was adding a line break before the final } if the replacement text
contained #, because otherwise the } would be commented out.
But to find the # it was using strchr, which stops at the first null.
So eval "s//'\0'#/e" would fail.
It makes little sense to me to check whether the replacement contains
# before adding the line break. It would be faster just to add the
line break without checking.
But then I discovered this bug:
s//"#" . <<END/e;
foo
END
__END__
Can't find string terminator "END" anywhere before EOF at - line 1.
So now I have two bugs to fix.
The easiest solution seems to be to omit the line break and make the
comment parser skip the } at the end of a s///e replacement.

toke.c: PL_in_eval purge
Many uses of PL_in_eval in toke.c are redundant.
PL_in_eval indicates not that we are parsing a string eval, but that
we are being called from an eval, whether stringy on not. Even if
PL_in_eval were only for string eval, it would still not indicate that
we are parsing a string eval, because of eval 'require'.
This commit removes redundant uses of it (making things theoretically
slightly faster).
