[mips] Add initial support for NaN2008 in the back-end.

This is so that EF_MIPS_NAN2008 is set if we are using IEEE 754-2008
NaN encoding (-mnan=2008). This patch also adds support for parsing
'.nan legacy' and '.nan 2008' assembly directives. The handling of
these directives should match GAS' behaviour i.e., the last directive
in use sets the ELF header bit (EF_MIPS_NAN2008).

The '.set mips64' directive enables the feature Mips:FeatureMips64

to the use of -mips64 from the command-line. The reason for this

The directive '.option pic2' enables PIC from assembly source.
At the moment none of the macros/directives check the PIC bit

expansion of macros like 'la' depend on the relocation model.

This has a few advantages:
* Only targets that use a MCTargetStreamer have to worry about it.
* There is never a MCTargetStreamer without a MCStreamer, so we can use a

This reverts commit r200064 and r200051.

r200064 depends on r200051.

r200051 is broken: I tries to replace .mips_hack_elf_flags, which is a good
thing, but what it replaces it with is even worse.

The new emitMipsELFFlags it adds corresponds to no assembly directive, is not
marked as a hack and is not even printed to the .s file.

The patch also introduces more uses of hasRawTextSupport.

The correct way to remove .mips_hack_elf_flags is to have the mips target
streamer handle the default flags (and command line options). That way the
same code path is used for asm and obj. The streamer interface should *really*
correspond to what is printed in the .s file.

[Mips] TargetStreamer ELF flag Support for default and commandline options.

This patch uses a common MipsTargetSteamer interface for both
MipsAsmPrinter and MipsAsmParser for recording default and commandline
driven directives that affect ELF header flags.

It has been noted that the .ll tests affected by this patch belong in
test/Codegen/Mips. I will move them in a separate patch.

Also, a number of directives do not get expressed by AsmPrinter in the
resultant .s assembly such as setting the correct ASI. I have noted this
in the tests and they will be addressed in later patches.
