[ELF] Move `# REQUIRES:` line to the top llvm-svn: 335625

# REQUIRES: mips
[ELF][MIPS] Add lazy relocation support for MIPS The patch adds lazy relocation support for MIPS and R_MIPS_26 relocation handing. R_MIPS_26 relocation might require PLT entry creation. In that case it is fully supported by the patch. But if the relocation target is a local symbol we need to use a different expression to calculate the relocation result. This case is not implemented yet because there is no method to get know the kind of relocation target in the `relocateOne` routine.

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651
