Sign extend 32-bit register values and Bug #3055

long in java is 64-bit, and 32-bit register value should be sign
extended.  We override Register.get() in Isa to do sign extension for
Ia32 and PPC(32-bit platforms).

2006-09-06  Yao Qi  <qiyaoltc@cn.ibm.com>
 
	* IsaPPC.java (get): Sign extend 32-bit value to 64-bit.
	* IsaIA32.java (get): Likewise.

	* TestRegs.java: Test sign extension on I386.

	* Syscall.java (printReturn): Do not cast returnCode to int. 

2006-09-05  Yao Qi  <qiyaoltc@cn.ibm.com>
 
	* funit-ia32-regs.S (main): Set %edx to -4 for sign extension
	test.

Please review this patch, and comments are welcome.  Thanks!
