* blockframe.c (frame_address_in_block): New function extracted
from get_frame_block().
(get_frame_block): Use frame_address_in_block().
(block_innermost_frame): Use frame_address_in_block() to match
the frame pc address against the block boundaries rather than
the frame pc directly. This prevents a failure when a frame pc
is actually a return-address pointing immediately after the end
of the given block.
