[patch] Cleanup fortran/convert.c

[Steven Bosscher <stevenb dot gcc at gmail dot com>]

Hi,

This cleans up some remnants of the ancestors of fortran's convert.c,
which was copied from GNAT IIRC.

I would bootstrap&test this, but trunk appears to be broken for
x86_64-linux right now (ICE in patch_jump_insn). But I can post this
for review, at least.

OK for trunk, after bootstrap+test?

Ciao!
Steven


	* Make-lang.in (convert.o): Depend on convert.h.
	* convert.c: Header and comment cleanups.
	(gfc_thruthvalue_conversion): Rename static function
	to truthvalue_conversion.  Do not use 'internal_error' from here,
	use 'gcc_unreachable' instead.
	(convert): Do not use 'error' for conversions to void, use
	'gcc_unreachable' instead.  Likewise for conversions to non-scalar
	types.  Do not hanlde ENUMERAL_TYPE, the front end never creates them.
	Clean up #if 0 code.
