1145 1) Fix trivial bug w/ transmitter empty interrupts that I introduced in the
last check-in.
2) Improve printed output from debugging-only uart_status() routine.		 sfurman 7746d 10h /or1k/tags/rel_11/
1144 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.		 sfurman 7748d 16h /or1k/tags/rel_11/
1143 Make UART transmitter-empty interrupts match both 16450 and 16550 behavior. sfurman 7749d 06h /or1k/tags/rel_11/
