[PATH] fix PR 13087, documentation does not follow IMA/IMI (all at once compiling)

[Andrew Pinski <pinskia at physics dot uc dot edu>]

This patch is make reality matches the documentation and also fixes a 
bug in the
process.  -save-temps used to not work when using compile at once aka 
gcc -c test.c test1.c -o test.o -c -save-temps would cause cc1 to error 
out and not produce anything because it would try to preprocess the 
source files together (e.g. cc1 -E test.c test1.c -o test.ii).

First I am sorry but I also included a patch to boolize some variables 
in gcc.c (some cleanup that
was needed as I was having some problems with variables not being 
"bool"), I can split it out if
need be.

I also found a bug in the way -### is handle when it comes to linker 
files, the driver warns no
matter what, I will try to see why this is.

This patch does not cause gcc to error out for supplying two files and 
"-E", that will be in the next patch.

Bootstrapped and regression tested on powerpc-apple-darwin7.0.0 (also 
bootstrapped with
--enable-intermodule).

ChangeLog:

	* gcc.c: Every where use false/true instead of FALSE/TRUE.
	(save_temps_flag): Boolize.	
	(build_search_list): Boolize first_time.
	(set_collect_gcc_options): Likewise.
	(print_multilib_info): Boolize print_at.
	
	PR driver/13087
	* gcc.c (default_compilers) <@c>: Do not run cc1 on the
	preprocessed source if -save-temps.	Do not run the
	assembler on the asm if -tranditional-cpp.
	(struct infile): Add incompiler, temp_filename, and compiled fields.
	(preprocessing): New variable to track when using -save-temps on a 
source.
	(assembly_input): New variable to track if an inputfile is an assembly 
file.
	(have_c): New variable.
	(have_o): Likewise.
	(traditional_cpp_flag): Likewise.
	(capital_e_flag): Likewise.
	(process_command): Change have_c and have_o to global static variables.
	Process also -traditional-cpp and -E.
	(do_spec_1): Create new temp file for each source file for all
	at once compiling.
	Save the temp_filename into infiles's temp_filename.
	<case 'i'>: Only do the combine of inputs when not preprocessing
	Only add files that have the same language as the input_file_compiler
	and that is not a linker flag.
	(main): Allow `gcc test.c test1.c -o test' use compile all at once.
	Separate out the creation of the intermediate files (fixes all at once
	and -save-temps).
	Do not lookup the compiler, use the cached one in infiles.

PS hopefully I did the changelog right :).
