Speed up gdb when running with serial targets:
When generating backtraces, the prologue of each function is scanned
at least three times by architecture-independent code, e.g. to
determine offsets of saved registers, identify frameless functions,
etc. This new code adds straightforward caching of the information
gleaned by or1k_scan_prologue() on a per-frame basis rather than
storing it in global static variables. (This benefits both JTAG and
serial gdb targets, though the JTAG target runs fast enough that it is
not particularly needed.)
When the register set is dumped by the serial target, e.g. at any
breakpoint or interrupt, the 32 vector/FP registers were included in
the dump (each 8 bytes long), though they aren't implemented. The new
code tells gdb that unimplemented registers have zero length in the
dump. |

Initialize or1k_implementation with reasonable defaults for the number
of implementation registers. This doesn't affect the jtag or sim
targets at all because those values are always overwritten when
or1k_implementation is initialized. However, it is necessary when
connecting to remote gdb stubs through a serial port or socket, since
or1k_implementation is not yet initialized for those targets. |

Fix stack-walking code in or1k_frame_chain() and or1k_skip_prologue()
to expect the function prologue that or32 gcc currently emits, rather
than a previous incarnation of the or1k ABI. |
