parse NOP instructions. I added the new table entries for the NOP for the
plain NOP, Yield, WFE, WFI, and SEV variants. Modified the opcode emulation
function EmulateInstructionARM::EmulateMOVRdSP(...) to notify us when it is
creating a frame. Also added an abtract way to detect the frame pointer
register for both the standard ARM ABI and for Darwin.
Fixed GDBRemoteRegisterContext::WriteAllRegisterValues(...) to correctly be
able to individually write register values back if case the 'G' packet is
not implemented or returns an error.
Modified the StopInfoMachException to "trace" stop reasons. On ARM we currently
use the BVR/BCR register pairs to say "stop when the PC is not equal to the
current PC value", and this results in a EXC_BREAKPOINT mach exception that
has 0x102 in the code.
Modified debugserver to create the short option string from long option
definitions to make sure it doesn't get out of date. The short option string
was missing many of the newer short option values due to a modification of
the long options defs, and not modifying the short option string.
