When WriteFragmentData() case FT_align called
Asm.getBackend().writeNopData() is called, nothing
is done since Mips implementation of writeNopData just
returned "true".

For some reason this has not caused problems in 32 bit
mode, but in 64 bit mode it caused an assert when processing
multiple function units.

The test case included will assert without this patch. It
runs twice with different flags to prevent false positives
due to changes in code generation over time.

It takes advantage of r159299 which introduces relocation support for N64. 
elf-dump needed to be upgraded to support N64 relocations as well.

This passes make check.

This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

The test case checks for both big and little endian flavors.

MachineOperand MO is of an unexpected type.

These changes allow us to compile big endian from the command line for 32 bit
Mips targets. This patch will result in code and data actually being produced
in the correct endianess.

avoid including ADT/Triple.h in many places when the target specific bits are

make the addend fixup code a bit more generic

Patch by Jack Carter.

Whether a fixup needs relaxation for the associated instruction is a
target-specific function, as the FIXME indicated. Create a hook for that
and use it.

"With this patch we can now generate runnable Mips code through LLVM
direct object emission. We have run numerous simple programs, both C
and C++ and with -O0 and -O3 from the output. The code is not production
ready, but quite useful for experimentation." Patch and message by
