Log Message:
-----------
add OPpCONST_LINE flag to aid deparsing
Code like
my $line = __LINE__;
was being deparsed as
my $line = '42';
because __LINE__ is converted by the lexer into an ordinary OP_CONST
whose SV is just a plain string holding the line number.
This commit adds a flag, OPpCONST_LINE, to OP_CONST, which is set to
indicate that this OP_CONST was created from a __LINE__ construct.
Deparse.pm then uses this new flag to print out the literal string
"__LINE__" rather than the constant's actual value.
This fixes one failing test file under
cd t; ./TEST -deparse
and removes one (but not all) sources of failure from three others.
