RFR: 6879063: SA should use hsdis for disassembly

Hi, all

   Can I have you code review of
   6879063: SA should use hsdis for disassembly

http://cr.openjdk.java.net/~minqi/6879063 
<http://cr.openjdk.java.net/%7Eminqi/6879063/>

   The SA has Java based disassemblers for x86 and sparc but amd64.  
Instead of porting to amd64 we should switch over to using hsdis for it 
like the JVM does.  This requires a new entry point into hsdis, 
decode_instructions_virtual, which separates the address of the code 
being disassembled from the buffer containing the code.  The existing 
uses of decode_instructions have been updated to use the new interface 
and SA Disassembler has Java native methods that call into hsdis and 
call back up to Java to perform the disassembly. Also changed makefile 
for hsdis build for both(i386/amd64).

   All the old disassembler logic was deleted since it's incompatible 
with the new disassembly interface. Also deleted are dbx based SA 
interface and few other dead files.

   Tested by dumping full assembly from core files.
