[PATCH] sim: tests: support .S/.c files

[Mike Frysinger <vapier at gentoo dot org>]

Rather than requiring all sim tests to be preprocessed .s files, add
support for .S and .c files so we can easily write code using a higher
level language like C.

	* sim-defs.exp: Support cc tag in test files.
	(run_sim_test): Support global_cc_options in boards files.  Convert
	assembler options into compiler options (c_as_options) with -Wa.
	Convert linker options into compiler options (c_ld_options) with -Wl.
	Compile .c and .S files into .x programs.
