[RFA] Add parse_dwarf2_calling_convention functionality

[Corinna Vinschen <vinschen at redhat dot com>]

Hi,

the second patch to prepare the calling convention stuff.  It just adds
the parse_dwarf2_calling_convention functionality to gdbarch.  The
below patch contains only the patch to gdbarch.sh (not the auto-generated
gdbarch.[ch]) and the new default_parse_dwarf2_calling_convention function
in arch-utils.

Ok to apply?


Corinna

	* gdbarch.sh (parse_dwarf2_calling_convention): New method.
	* gdbarch.h, gdbarch.c: Re-generate.
	* arch-utils.c (default_parse_dwarf2_calling_convention): New function.
	* arch-utils.h (default_parse_dwarf2_calling_convention): New extern
	declaration.
