Previously thumb bits were only checked for external relocations (thumb to arm code and vice-versa). This patch adds detection for thumb callees in the same section asthe (also thumb) caller. The MachO/Thumb test case is updated to cover this, and redundant checks (handled by the MachO/ARM test) are removed. llvm-svn: 331838
