[ELF][MIPS] Produce a correct and complete set of MIPS ELF header flags The patch extends the `getMipsEFlags` function. Now in that function we iterate over all object files, parse ELF header flags and merge them. If a file is incompatible with previously analyzed ones we show an error or warning. That can happen if, for example, we try to link files with incompatible ABI, ISA, NAN encoding etc. There is an alternative solution. We can check and merge flags and reject incompatible input modules in the `isCompatible` function which is called from the `SymbolTable::addFile` method. But in that case we have to save and keep somewhere a merged ELF flags combination to use it later in the writer. Differential Revision: http://reviews.llvm.org/D23161 llvm-svn: 277911

[ELF][MIPS] Take into account combination of EF_MIPS_ARCH and EF_MIPS_MACH flags while checking ISA compatibility MIPS ISA encoded using two ELF flags: general architecture flag like EF_MIPS_ARCH_32, EF_MIPS_ARCH_64R6 etc and optional machine variant flag like EF_MIPS_MACH_4111, EF_MIPS_MACH_OCTEON3 etc. When we check compatibility between two input files and deduce ELF flags for generated output we need to take into account both of these flags. llvm-svn: 278230
