[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

Reland "[MC][ELF] Work around R_MIPS_LO16 relocation handling problem" This fixes PR49821, and avoids "ld.lld: error: test.o:(.rodata.str1.1): offset is outside the section" errors when linking MIPS objects with negative R_MIPS_LO16 implicit addends. ld.lld handles R_MIPS_HI16/R_MIPS_LO16 separately, not as a whole, so it doesn't know that an R_MIPS_HI16 with implicit addend 1 and an R_MIPS_LO16 with implicit addend -32768 represents 32768, which is in range of a MergeInputSection. We could introduce a new RelExpr member (like R_RISCV_PC_INDIRECT for R_RISCV_PCREL_HI20 / R_RISCV_PCREL_LO12) but the complexity is unnecessary given that GNU as keeps the original symbol for this case as well. Adds a new test case for PR49821, and also updates two other test cases that are affected by this change. Reviewed By: atanasyan, MaskRay Differential Revision: https://reviews.llvm.org/D101773
