This provides rudimentary testing of the llvm-c api.
The following commands are implemented:
* --module-dump
Read bytecode from stdin - print ir
* --module-list-functions
Read bytecode from stdin - list summary of functions
* --module-list-globals
Read bytecode from stdin - list summary of globals
* --targets-list
List available targets
* --object-list-sections
Read object file from stdin - list sections
* --object-list-symbols
Read object file from stdin - list symbols (like nm)
* --disassemble
Read lines of triple, hex ascii machine code from stdin - print disassembly
* --calc
Read lines of name, rpn from stdin - print generated module ir
