[driver] Don't blindly accept all -g options. rdar://10383444 llvm-svn: 143732

Improve support for -g options accepted by Clang: 1. Accept flags -g[0-3], -ggdb[0-3], -gdwarf-[2-4] and collapse them to simple -g (except -g0/-ggdb0). 2. Produce driver error on unsupported formats (-gcoff, -gstabs, -gvms) and options (-gtoggle). 3. Recognize and ignore flags -g[no-]strict-dwarf, -g[no-]record-gcc-switches. llvm-svn: 158906

This patch adds a new Clang compiler flag "-gline-tables-only". It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.
