sim: tests: support .S/.c files

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.

+       * lib/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.
