[PATCH] Add support for Lattice Mico32 (LM32)

Thanks very much for submitting this port.  I have applied it to the 
sources, although I did make a few changes:

* There was a compile time warning/error:

  .../opcodes/lm32-asm.c: In function 'parse_imm':
  .../opcodes/lm32-asm.c:74: error: pointer targets in passing argument 
4 of 'cgen_parse_signed_integer' differ in signedness

  Changing 'value' (declared at line 72) to a signed long fixes this 
problem.

* We are no longer using the PARAMS macro, so I fixed the places where 
it was being used.

* The copyright notices in the new files did not actually assign the 
copyright to the FSF and they were using version 2 of the GPL, whereas 
we are now using version 3.

* The dependencies for the generated files in the opcodes directory were 
set to point to the wrong place (cgen/cpu instead of cpu/).

* You directly edited the bfd-in2.h header file, which is an 
auto-generated file.  You needed to add the LM32 relocations to the 
bfd/reloc.c file and then regenerate bfd-in2.h.

* There were a few minor formatting issues (whitespace, comments, 
function prototypes).


Apart from those points everything else was fine.  The patch applied 
cleanly and did not introduce any new failures, so welcome to the 
binutils team!

Cheers
   Nick
