[fpc-pascal] Access to compiler's internal data structures

[Kenneth Cochran]

My goal is to make it an IDE expert so the CodeTools parser sounds ideal.
Just didn't want to reinvent the wheel. I also wanted to avoid the problem
Delphi has been plagued with for years, that is, CodeInsight flagging code
with syntax errors that the compiler readily accepts because they use
different parsers.
