[lto] More check-gcc fixes

[Diego Novillo]

This fixes 7 failures in check-gcc.  The streamer was not
emitting all the information for every basic block.

This converts some compile errors into runtime errors, but I'm
addressing those with an upcoming patch.

Tested on x86_64.


Diego.


	* lto-function-out.c (output_bb): Write basic block
	fields 'count', 'loop_depth', 'frequency' and 'flags'.
	* lto-function-in.c (input_bb): Corresponding changes.
