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

# REQUIRES: mips
[ELF][MIPS] Set GP0 value to zero in case of relocatable object generation LLD does not update relocations addends when generate a relocatable object. That is why we should not write a non-zero GP0 value into the .reginfo and .MIPS.options sections. And we should not accept input object files with non-zero GP0 value because we cannot handle them properly. llvm-svn: 282716

[ELF][MIPS] Do not accept non-zero GP0 value for relocatable object only Follow-up to r282716. Reject input files with non-zero GP0 value only in case of relocatable object generation. In other case we can handle arbitrary GP0 value so it does not have a sense to make the restriction so wide. llvm-svn: 283194

Don't make _gp absolute. _gp points to a position in the file, so it is not really absolute. It is also simpler to not force it to be absolute, so if there is no strong ABI requirement we should not do it. llvm-svn: 313333
