"load data" statements were written to the binlog as a mix of the original statement and bits recreated from parse-info. This relied on implementation details and broke with IGNORE_SPACES and versioned comments. We now completely resynthesize the query for LOAD DATA for binlog (which among other things normalizes them somewhat with regard to case, spaces, etc.). We have already parsed the query properly, so we make use of that rather than mix-and-match string literals and parsed items. This should make us safe with regard to versioned comments, even those spanning multiple tokens. Also no longer affected by IGNORE_SPACES.
