  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.

This tool is only invoked if -O (or -O0-3) is specified on the command line.

  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.

  Log Message:
  -----------
  Document a peculiarity in CM3 IR that reflects call-site copy.

For parameters of struct types, (which could be any static sized
in-memory aggregate, but used only for records and arrays), only the
call site has IR operators that indicate that a copy should be made,
thus effectively passing by value.  There is no IR indication of
by-value passing at procedure entry, making it easy for a back end to
do call site copy and, at best, subtle to do it at procedure entry.

Document this is M3CG_Ops.i3.

  -----------
  Fix a bug passing records by value in indirect calls.

For indirect calls, structs (static-sized records & arrays) passed
by value didn't get the llvm byval attribute, which causes llvm to
insert call-site copy.  Worked for direct calls.  Indirect calls
in cm3 IR do not have enough information to know when to add byval.

Changed to do away altogether with the byval attribute and instead
generate explicit call-site code to make the copy, in pop_struct.

  Set mem_type to Struct as per the comment

Array, Record and (Set types greater than word size) generate pop_struct
operators for their calls by value. This results in a declare_param for
each of these types in the case of directly callable functions from imported procedures.
These params were being declared as Addr resulting in a type mismatch. Also the declaration in
the Interface was Addr but in the Module was Struct resulting in some ambiguity.

  Log Message:
  -----------
  More versatile interface to CopyOpenArray.

Also misc comments.

NOTE: It turns out that a call site open array copy is not needed.
For a READONLY array formal, the only time a call site copy is
required is when the actual is a nondesignator.  This can only
be an array constructor or function result.  In either case, the
size is statically known, so CG's GenCopy can be used, even when
the formal and/or actual is open.

This is very fortunate, because CopyOpenArray needs to generate
a call to RTS' NewTracedArray, and that would be a nested call,
which would be quite unpleasant to avoid.

NOTE2: Except for prolog-located copy of an open array, (which
happens when the formal is VALUE open array), all by-value copying
of in-memory types is done at the call site.  This is unfortunate
from a performance standpoint, because it can make for poor use of
temp space, not to mention duplication of copy code at multiple
calls to the same procedure.  But changing this would upset binary
compatability with previously compiled code and such things as C
bindings.

  Add test p032, passing of array parameters.

Test passing of array parameters, fixed and open, in all three modes.

For READONLY mode, this is subtle.  According to Modula3, only
nondesignators passed by value in READONLY mode.  (Anything that
is assignable is passed by reference, and anything not assignable
is statically illegal.)  The only array nondesignators are constants
and function results, neither of which is aliasable, so they are
regarded as already being copies and passed by reference at the low
level.
