[PATCH] [Mips][ABI]The ELF container needs to depend on the ABI rather than the target triple.

[Vladimir Medic]

As suggested by Eric, ABI info  is taken from MCTargetOptions which is passed to createAsmBackend method. Definitions of these methods for all targets have been extended with this parameter to keep the build sanity. For the Mips target ABI info is extracted to create elf32/64 object file. Also, the way that extracts the target triple information from ELF header is changed for Mips platform. This patch is followed with a necessary change in clang driver.
