The N32 ABI uses RELA relocation format, do not use 3-in-1 relocation's encoding, and uses ELFCLASS32. This change passes the `IsN32` flag to the `MCAsmBackend` to distinguish usage of N32 ABI. We still do not handle some cases like providing the `-target-abi=o32` command line option with the `mips64` target triple. That's why elf_header.s contains some "FIXME" strings. This case will be fixed in a separate patch. Differential revision: https://reviews.llvm.org/D37960 llvm-svn: 313873
