[PATCH 0/2] Add recording support for the ISA 3.1 Powerpc instructions

[Carl Love <cel@us.ibm.com>]

GDB maintainers:

The gdb record functionality does not have support for the the Powerpc
ISA 3.1 instructions.  

The first patch in this series will add the missing support to record
the registers for each of the ISA 3.1 instructions.

The second patch in the series adds two test cases.  The first test
case verifies the recording works for a few of the ISA 2.06
instructions.  The second case verifies recording of a few ISA 3.1
instructions.

I have used the Valgrind ISA 3.1 testsuite to verify that all of the
ISA 3.1 instructions are recognized by gdb record.  Additionally, I
manually ran gdb stoping at the Valgrind test function for each of the
new instructions.  I then verified that all of the expected registers
changed and were then restored when the instruction was executed in
reverse.  Basically, the test process consisted of stopping at the isa
instruction, issue the gdb command record command, info registers all
saving the output file 1, si,  info registers all saving the output
file 2, reverse-stepi, info registers all saving the output file 3.  I
then diffed files 1 and 2 to verify the test changed all of the
registers specified in the ISA. Finally, diff files 1 and 3 to verify
all of the registers were restored.
