[llvm-commits] [Mips] Resubmit of big endian direct object patch

[Carter, Jack]

Reduced big endian patch

big_endian_2.patch

These changes allow us to compile big endian from the
commandline for 32 bit Mips targets.

The biggest changes are to classes that must convey
different target attributes such as endianess.

test/MC/Mips/elf_basic.s

Changed to use llvm-mc instead of llc

**********************
lib/Target/Mips/MCTargetDesc/MipsMCTargetDesc.cpp

Changed registries to reflect endianess.

Formatted to fit within the 80 character rule.

**********************
lib/Target/Mips/MCTargetDesc/MipsAsmBackend.cpp

Added IsLittle data member to MipsAsmBackend

Added endianess flag to parameters.

**********************
lib/Target/Mips/MCTargetDesc/MipsELFObjectWriter.cpp

Added endianess flag to parameters.

**********************
lib/Target/Mips/MCTargetDesc/MipsMCTargetDesc.h

Added endian specific create MipsMCCodeEmitter variants.

Changed the names of createMipsAsmBackend variants to be
consistant.

Added endian parameter to createMipsELFObjectWriter().
