Fix loop-level instrumentation + more (#32)

- fix loop-level instrumentation
- support loop instrumentation w/o debug symbols via loop number
- improve module_function messages
- serialize num_basic_blocks
- serialize num_outer_loops
- serialize is_num_instructions_constrained
- serialize is_loop_num_instructions_constrained
- updated transpose example to use uniform_int_distribution
- added transpose loop test
- added fail regexes for tests which enable loop instrumentation
- use module->getFullName in get_loop_file_line_info
- use module->getFullName in get_func_file_line_info
- use module->getFullName in get_basic_block_file_line_info
