[ELF] Introduce Thunk reuse compatibility
On ARM the interworking thunks are only produced for branch instructions
that can't be changed into a blx instruction so only Thumb callers would
call Thumb thunks and only ARM callers would call ARM thunks. With range
extension thunks branch and link instructions may need a Thunk. These
instructions can be rewritten as a blx and can use either ARM or Thumb
thunks.
We introduce an isCompatibleWith() function so that a caller can check if
an existing Thunk is compatible before reusing it.
