    M clang/lib/Driver/ToolChains/Clang.cpp
    M clang/test/CodeGen/split-debug-inlining.c
    M clang/test/Driver/split-debug.c

  Log Message:
  -----------
  Make -f[no-]split-dwarf-inlining CC1 default align with driver default (no inlining)

This makes CC1 and driver defaults consistent.
In addition, for more common cases (-g is specified without -gsplit-dwarf), users will not see -fno-split-dwarf-inlining in CC1 options.

Verified that the below is still true:

* `clang -g` => `splitDebugInlining: false` in DICompileUnit
* `clang -g -gsplit-dwarf` => `splitDebugInlining: false` in DICompileUnit
* `clang -g -gsplit-dwarf -fsplit-dwarf-inlining` => no `splitDebugInlining: false`
