[ELF] - Partial support of --gdb-index command line option (Part 1). In this patch partial gdb_index section is created. For costructing the .gdb_index section 6 steps should be performed (details are in SplitDebugInfo.cpp file header), this patch do first 3: Creates proper section header. Fills list of compilation units. Types CU list area is not supposed to be supported, so it is ignored and therefore can be treated as implemented either.

[ELF] - Remove dependency on precompiled inputs from -gdb-index testcases. Previously we used precompiled objects in gdb-index.s and debug-gnu-pubnames.s testcases. We can avoid that. Differential revision: https://reviews.llvm.org/D35360 llvm-svn: 308005

Remove 'z' in .zdebug when decompressing a section. When decompressing a compressed debug section, we drop SHF_COMPRESSED flag but we didn't drop "z" in ".zdebug" section name. This patch does that for consistency. This change also fixes the issue that .zdebug_gnu_pubnames are not dropped when we are creating a .gdb_index section. llvm-svn: 324949
