test/MC/ARM/ltorg-darwin.s

@ This test has a partner (ltorg.s) that contains matching
@ tests for the .ltorg on linux targets. We need separate files
@ because the syntax for switching sections and temporary labels differs
@ between darwin and linux. Any tests added here should have a matching
@ test added there.
