* toplev.c (documented_lang_options): Recognize -include,
-imacros, -iwithprefix, -iwithprefixbefore.
* cpplib.c (cpp_start_read): Process -imacros and -include
switches at the same time and in command-line order, after
initializing the dependency-output code. Emit properly nested
#line directives for them. Emit a #line for the main file
before processing these switches, and don't do it again
afterward.
