shift flag_next/gnu_runtime to modern opts system.
gcc:
* doc/tm.texi.in (NEXT_OBJC_RUNTIME): Update macro description.
* doc/tm.texi: Regenerate.
* flags.h (flag_next_runtime): Remove references.
* toplev.c: Likewise.
* defaults.h (NEXT_OBJC_RUNTIME): Provide default.
* gccspec.c (lang_specific_driver): Adjust use of NEXT_OBJC_RUNTIME.
* config/darwin.c (darwin_override_options): Provide default
Objective-C abi settings and target conflict checks.
* config/darwin.h (SUBTARGET_C_COMMON_OVERRIDE_OPTIONS): Remove unused
code. Adjust indenting.
gcc/c-family:
* c.opt (fgnu-runtime): Provide full description.
(fnext-runtime): Likewise.
