Cleanup relocation sorting for ELF.
We want the order to be deterministic on all platforms. NAKAMURA Takumi
fixed that in r181864. This patch is just two small cleanups:
* Move the function to the cpp file. It is only passed to array_pod_sort.
* Remove the ppc implementation which is now redundant

Remove MCELFObjectTargetWriter::adjustFixupOffset hack
Now that PowerPC no longer uses adjustFixupOffset, and no other
back-end (ever?) did, we can remove the infrastructure itself
(incidentally addressing a FIXME to that effect).

This patch reworks how llvm targets set
and update ELF header e_flags.
Currently gathering information such as symbol,
section and data is done by collecting it in an
MCAssembler object. From MCAssembler and MCAsmLayout
objects ELFObjectWriter::WriteObject() forms and
streams out the ELF object file.
This patch just adds a few members to the MCAssember
class to store and access the e_flag settings. It
allows for runtime additions to the e_flag by
assembler directives. The standalone assembler can
get to MCAssembler from getParser().getStreamer().getAssembler().
This patch is the generic infrastructure and will be
followed by patches for ARM and Mips for their target
specific use.

Initial TOC support for PowerPC64 object creation
This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).
The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.

The ELF relocation record format is different for N64
which many Mips 64 ABIs use than for O64 which many
if not all other target ABIs use.
Most architectures have the following 64 bit relocation record format:
typedef struct
{
Elf64_Addr r_offset; /* Address of reference */
Elf64_Xword r_info; /* Symbol index and type of relocation */
} Elf64_Rel;
typedef struct
{
Elf64_Addr r_offset;
Elf64_Xword r_info;
Elf64_Sxword r_addend;
} Elf64_Rela;
Whereas N64 has the following format:
typedef struct
{
Elf64_Addr r_offset;/* Address of reference */
Elf64_Word r_sym; /* Symbol index */
Elf64_Byte r_ssym; /* Special symbol */
Elf64_Byte r_type3; /* Relocation type */
Elf64_Byte r_type2; /* Relocation type */
Elf64_Byte r_type; /* Relocation type */
} Elf64_Rel;
typedef struct
{
Elf64_Addr r_offset;/* Address of reference */
Elf64_Word r_sym; /* Symbol index */
Elf64_Byte r_ssym; /* Special symbol */
Elf64_Byte r_type3; /* Relocation type */
Elf64_Byte r_type2; /* Relocation type */
Elf64_Byte r_type; /* Relocation type */
Elf64_Sxword r_addend;
} Elf64_Rela;
The structure is the same size, but the r_info data element
is now 5 separate elements. Besides the content aspects,
endian byte reordering will be different for the area with
each element being endianized separately.
I treat this as generic and continue to pass r_type as
an integer masking and unmasking the byte sized N64
values for N64 mode. I've implemented this and it causes no
affect on other current targets.
This passes make check.

entries in the relocation table before they are written out to the file.
