[ELF][MIPS] Handle section symbol points to the .MIPS.options / .reginfo section MIPS .reginfo and .MIPS.options sections are consumed by the linker, and the linker produces a single output section. But it is possible that input files contain section symbol points to the corresponding input section. In case of generation a relocatable output we need to write such symbols to the output file. Fixes bug 27878. Differential Revision: http://reviews.llvm.org/D20688 llvm-svn: 270910

[ELF][MIPS] Convert .reginfo and .MIPS.options sections to synthetic input sections Previously, we have both input and output sections for .reginfo and .MIPS.options. Now for each such sections we have one synthetic input sections: MipsReginfoSection and MipsOptionsSection respectively. Both sections are handled as regular sections until the control reaches Writer. Writer then aggregates all sections whose type is SHT_MIPS_REGINFO or SHT_MIPS_OPTIONS to create a single synthesized input section. In that moment Writer also save GP0 value to the MipsGp0 field of the corresponding ObjectFile. This value required for R_MIPS_GPREL16 and R_MIPS_GPREL32 relocations calculation.

# PR 27878
#
# Input object file created using the following script:
# % cat t.s
# .text
# nop
# % as -mabi=64 -mips64r2 t.s
# RUN: ld.lld -r %p/Inputs/mips-options.o -o %t.o
[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
