It is not necessary to call get_compiler_info before calling test_compiler_info, and, after recent commits that removed setting up the gcc_compiled, true, and false globals from get_compiler_info, there is now no longer any need for any test script to call get_compiler_info directly. As a result every call to get_compiler_info outside of lib/gdb.exp is redundant, and this commit removes them all. There should be no change in what is tested after this commit.
