PATCH: Fix toplev.c breakage on PA after eh merge

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

Here is a possible fix for the problem noted here:
<http://gcc.gnu.org/ml/gcc-patches/2001-05/msg00860.html>.  I moved the
code to open the assembler and aux info files before the data initialization.
I also included dwarf2asm.h because there is no prototype for
dw2_output_indirect_constants ().  Should this be ifdef'd?

The patch is untested as there is still more breakage to resolve:

	* toplev.c: Include dwarf2out.h.
	(compile_file): Open aux_info_file and asm_out_file before
	initializing data.
