bd8d853f77 gold: Add view and view_size parameters to is_call_to_non_split. 
This is needed by s390 split-stack support, to distinguish call
and load-address relocations.

gold/ChangeLog:

	* i386.cc (Target_i386::is_call_to_non_split): Add view and view_size
	parameters.
	* reloc.cc (Sized_relobj_file::split_stack_adjust_reltype): Pass view
	and view_size to is_call_to_non_split.
	* target.cc (Target::is_call_to_non_split): Add view and view_size
	parameters.
	* target.h (class Target): Likewise.

4d625b70fc Refactor gold to enable support for MIPS-64 relocation format. 
For MIPS-64, the r_info field in the relocation format is
replaced by several individual fields, including r_sym and
r_type. To enable support for this format, I've refactored
target-independent code to remove almost all uses of the r_info
field. (I've left alone a couple of routines used only for
incremental linking, which I can update if/when the MIPS target
adds support for incremental linking.)

For routines that are already templated on a Classify_reloc class
(namely, gc_process_relocs, relocate_section, and
relocate_relocs), I've extended the Classify_reloc interface to
include sh_type (which no longer needs to be a separate template
parameter) as well as get_r_sym() and get_r_type() methods for
extracting the r_sym and r_type fields. For
scan_relocatable_relocs, I've extended the
Default_scan_relocatable_relocs class by converting it to a class
template with Classify_reloc as a template parameter. For the
remaining routines that need to access r_sym, I've added a
virtual Target::get_r_sym() method with an override for the MIPS
target.

In elfcpp, I've added Mips64_rel, etc., accessor classes and
corresponding internal data structures. The MIPS target uses
these new classes within its own Mips_classify_reloc class.
The Mips64_ accessor classes also expose the r_ssym, r_type2,
and r_type3 fields from the relocation.

These changes should be functionally the same for all but the
MIPS target.
