Manman Ren 17bdb0f815 Set default Dwarf Version for -gline-tables-only on Darwin to 2.
We are still using Dwarf Version 2 for Darwin systems, make it consistent
with -gline-tables-only.

This should fix an internal buildbot.

Manman Ren 38db092083 Debug Info: set default to gdwarf-2 for Darwin.
Darwin systems currently do not support dwarf version 3 or above. When we are
ready, we can bump the default to gdwarf-4 for Darwin.

For other systems, the default is dwarf version 3, if everything goes smoothly,
we can bump the version to 4.

Manman Ren 9691f7fa35 Debug Info: support for gdwarf-2 gdwarf-3 gdwarf-4
These options will add a module flag with name "Dwarf Version".
The behavior flag is currently set to Warning, so when two values disagree,
a warning will be emitted.

later with dwarf4 type hashing.

Alexey Samsonov f50a9ffd0b 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.

Alexey Samsonov dda3a7f914 Make Clang driver pass the last option from -g group to the compiler.
Leave a better fixme for different debug info flags

Alexey Samsonov 74a3868dbb 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.

NAKAMURA Takumi 5a5bb93004 test/Driver/debug-options*.c: Tweak r147819 to split out another cc1as-sensitive test. gcc driver is invoked for assembling on cygming.

Eric Christopher fc3ee566eb Add -g to the cc1as flags only if we're dealing with an original
source file. Otherwise -g -save-temps will error out on the compile
of any .c file.

Fixes about 4000 of the errors in the clang-tests gdb test suite.
