It's still there:
-P causes your script to be run through the C preprocessor before
compilation by Perl. (Because both comments and cpp directives
begin with the # character, you should avoid starting comments with
any words recognized by the C preprocessor such as "if", "else", or
"define".)
These days, it's mostly only used for very special applications and
obfuscated code, as the C preprocessor isn't really designed for
preprocessing other languages (some Perl constructs confuse it), and of
course Perl's use of # as a comment character conflicts pretty badly with
the use of the preprocessor.
