[Clang] - Add '-gsplit-dwarf[=split,=single]' version for '-gsplit-dwarf' option. The DWARF5 specification says(Appendix F.1): "The sections that do not require relocation, however, can be written to the relocatable object (.o) file but ignored by the linker or they can be written to a separate DWARF object (.dwo) file that need not be accessed by the linker." The first part describes a single file split DWARF feature and there is no way to trigger this behavior atm. Fortunately, no many changes are required to keep *.dwo sections in a .o, the patch does that. Differential revision: https://reviews.llvm.org/D52296 llvm-svn: 346837

// REQUIRES: x86-registered-target
[Clang] Remove unused -split-dwarf and obsolete -enable-split-dwarf Summary: The changes in D59673 made the choice redundant, since we can achieve single-file split DWARF just by not setting an output file name. Like llc we can also derive whether to enable Split DWARF from whether -split-dwarf-file is set, so we don't need the flag at all anymore. The test CodeGen/split-debug-filename.c distinguished between having set or not set -enable-split-dwarf with -split-dwarf-file, but we can probably just always emit the metadata into the IR. The flag -split-dwarf wasn't used at all anymore. Reviewers: dblaikie, echristo Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D63167 llvm-svn: 364479
