 - gcc is not happy if we start a preprocessed file with
#line 1 "XXX" 1
 - Workaround by making sure file starts with a simple #line change.

Also, factored WriteLineInfo out.

Also, fixed bug where FileType was not being correctly updated.

Remove "NextDecl" from RecordDecl.  This change touches many files that where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration.

The motivation behind this change is that chaining the RecordDecls is simply unnecessary.  Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType.

For whatever the reason, x86 CallingConv::Fast (i.e. fastcc) was not passing scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries.
