Fix a couple gdb.dwarf2/ testcases with "clang -flto"
gdb.dwarf2/atomic-type.exp and gdb.dwarf2/ada-linkage-name.exp fail
when testing with "clang -flto" as compiler, like:
$ make check TESTS="gdb.dwarf2/ada-linkage-name.exp" RUNTESTFLAGS="CC_FOR_TARGET='clang -flto'"
because with -flto, functions that aren't referenced anywhere are not
emitted in the final binary. Fix it by adding uses of the functions.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/ada-linkage-name.c (main): Move to the bottom of the
file and add calls to first and second.
* gdb.dwarf2/atomic.c (main): Move to the bottom of the file and
add call to f.
