[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).

[llvm-readobj] Update tests because of changes in llvm-readobj behavior This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar

[mips] Fix ELF e_flags related to -mabicalls and -mplt. Summary: These options are not implemented yet but we act as if they are always given. The integrated assembler is driven by the clang driver so the e_flag test cases should match the e_flags emitted by GCC+GAS rather than GAS by itself.
