scan_heredoc could reallocate PL_parser->linestr's PV
Since f0e67a1 it was possible the freed buffer may be read from when
parsing a heredoc. This adds a call to lex_grow_linestr to grow the
buffer and ensure the pointers in PL_parser are updated.
The bug is pretty hard to reproduce, hence no test. I'm able to
reproduce it with the following:
perl -Meverywhere=re,debug -MParams::Util -e1
