op.c: Allow COW with folded constants under MAD
Under MAD builds, this copy of the SV can result in a redundant
string copy. Since we can take advantage of COW, letâs do so.
This really speeds up compilation of things like "a"x2**31
under MAD.
XXX This does not work because of the broken way the pads âworkâ;
it has to wait until after the sprout/padconst branch is merged.

sv.c: Remove overflow check in utf8 length cache
In order to make large values of pos() possible, the previous commit
enlarged the mg_len field of the magic struct. That field is also
used for cached utf8 length values. Since it is now large enough to
store any length the OS/compiler supports, the overflow never happens.

[perl #72766] Allow huge pos() settings
This is part of #116907, too. It also fixes #72924 as a side effect;
the next commit will explain.
The value of pos($foo) was being stored as an I32, not allowing values
above I32_MAX. Change it to SSize_t (the signed equivalent of size_t,
representing the maximum string length the OS/compiler supports).
This is accomplished by changing the size of the entry in the magic
struct, which is the simplest fix.
Other parts of the code base can benefit from this, too.
The regexp engine itself still cannot handle large strings, so being
able to set pos to large values is useless right now. This is but one
piece in a larger puzzle.

Add sv_pos_b2u_flags
This, similar to sv_pos_u2b_flags, is a more friendly variant of
sv_pos_u2b that works with 2GB strings and actually returns a
value instead of modifying a passed-in value in place through
a pointer.
The next commit will use this.
