applied Alexey Dejneka's fixes from sbcl-devel 2001-10-13..
..exported RETURN-PC-SAVE-OFFSET from SB!VM as per

..fixed PARSE-COMPILED-DEBUG-BLOCKS along the lines of
"debugger errors" message (DEBUG-FUNCTION vs.
DEBUG-FUN, argh!)
s/about-to-modify/about-to-modify-symbol-value/
INDEX is in SB-INT now, so it doesn't need package prefixes
