Fix uninitialized variable warnings.
Check for use of previously uninitialized variables; call gcc_unreachable().
Replace abort() with gcc_unreachable().

* config/microblaze/microblaze.cc
(microblaze_legitimize_address): Initialize 'reg' to NULL, check for NULL.
(microblaze_address_insns): Replace abort() with gcc_unreachable().
(print_operand_address): Same.
(microblaze_expand_move): Initialize 'p1' to NULL, check for NULL.
(get_branch_target): Replace abort() with gcc_unreachable().
