Since typeglobs may have the UTF8 flag set now, we need to avoid
testing SvCUR on a potential glob, as that would trip an assertion.

$[ remains as a variable. It no longer has compile-time magic.
At runtime, it always reads as zero, accepts a write of zero, but dies
on writing any other value.

sub_lval.t is for lvalue subs, not built-ins.

pp_substr contains this comment, which was added in perl 5.0 alpha 2
(commit 79072805bf63):
PUSHs(TARG); /* avoid SvSETMAGIC here */
Calling set-magic when substr returns an lvalue will cause its argu-
ment to be stringified even if the lvalue is not assigned to. That’s
why set-magic has to be avoided.
But the result is that utf8 caches (stored in magic) on TARG are not
reset properly.
Since substr lvalues now follow a different code path (and do not use
TARG at all), it’s perfectly safe to call set-magic at this point.
It’s also the right thing to do in case of other types of magic that
might get attached to TARG.

TEMP instead of using TARG. Made appropriate TODO tests live.

available for the pos and len arguments, with safe conversion to STRLEN where it's smaller than an IV.

(This is only a partial fix, since it doesn't handle lvalue substr)
