[perl #46499] [RFE] Allow comment lines in PIR .param list

Currently following PIR is failing because of the '#' in the '.param' list.

.sub main :main

  ( $S1 ) = my_sub( 'hello', 'world' )
  say $S1
.end

.sub my_sub
    .param string  str1
    #
    .param string  str3

    .local string hello
    hello = concat str1, str3

    .return( hello )
.end


This surprised me, as I expected that '#' lines would be ignored.
So I propose to tweak the PIR grammar such that comment lines are allowed
