* typinfo.pp: the newly introduced records were added into {$PACKRECORDS 1} area of effect, which effectively made all records packed, entirely defeating FPC_REQUIRES_PROPER_ALIGNMENT purpose.
* added alignment between TProcedureParam records, adjusted TProcedureSignature.GetParam() appropriately.
* ncgrtti.pas: added two missing alignments and removed a redundant one.
* tests/test/trtti9.pp: modified to use TProcedureSignature.GetParam() and endian-independent check for parameter flags.
