Inline breakpoints

gdb/ChangeLog:
yyyy-mm-dd  Pedro Alves  <palves@redhat.com>

	* inline-frame.c (stopped_by_user_bp_inline_frame): Replace PC
	parameter with a block parameter.  Compare location's block symbol
	with the frame's block instead of addresses.
	(skip_inline_frames): Pass the current block instead of the
	frame's address.  Break out as soon as we determine the frame
	should not be skipped.

gdb/testsuite/ChangeLog:
yyyy-mm-dd  Pedro Alves  <palves@redhat.com>

	* gdb.opt/inline-break.c (func_callee, func_caller): New.
	(main): Call func_caller.
