  Add command line support for disabling debugger output and extend optimization levels

Added support for -g0 to disable debugger information being built by the backend
this is primarily to enable developers to read the generated assembly and compare
output from cmc3g and llvm. The option is available for both gcc and clang.

Also added is support for -O0 -O1 -O2 -O3 optimisation levels which are passed to the
backend. O0 disables optimisation and the other levels are in line with gcc and llvm
llc and opt tools.

  -----------
  Allow llvm optimzation pass opt to be called at various optimization levels

The llvm opt tool does various IR to IR optimization transformations.
This tool is only invoked if -O (or -O0-3) is specified on the command line.

The file generated is basefile_opt.(mb|ib) and is deleted unless -keep
is also specified.

  Add source line info to abort procedure

llvm was not passing the source line to ReportFault to aid in runtime error
diagnosis.

Also removed a couple of warnings for unused vars.

  -----------
  Pass nodebug to cm3 for llvm tests

Currently M3CG_LLVM has problems with debugging. Passing -g0 in cm3 command
avoids the problem and allows proper testing using the llvm backend.

Note there may be another way to do this.

It also allows us to pass an optimisation level to the test if needed.
