Support Xilinx MicroBlaze processor - patch 2

[Joseph S. Myers]

There seem to be various GNU Coding Standards violations in this code.  
Functions in microblaze-dis.c seem generally to be missing comment them, 
and there are lots of function calls without a space between the function 
name and opening parenthesis.  Code formatting such as

+  if (inst == 0) {
+    return -1;
+  }

does not follow the standards for placing "{" either.  This patch also has 
C++ comments.
