* dwarf2out.c (output_fde): When doing hot/cold partitioning, use
	fde->dw_fde_begin as begin label instead of hot/cold label.
	Use LLSDAC label instead of LLSDA for second section lsda.
	(dwarf2out_do_cfi_startproc): Add SECOND argument.  Use LLSDAC
	label instead of LLSDA if it is true.
	(dwarf2out_begin_prologue, dwarf2out_switch_text_section): Adjust
	callers.
	* except.c (add_call_site, dw2_size_of_call_site_table): Add
	SECTION argument.  Use it as index into crtl->eh.call_site_record
	array.
	(dw2_output_call_site_table): Likewise.  Add CS_FORMAT argument,
	use it to determine how to print table entries instead of using
	#ifdef HAVE_AS_LEB128.  For SECTION > 0 use hot resp. cold
	label instead of normal begin label as base.
	(sjlj_assign_call_site_values): Adjust add_call_site caller.
	(convert_to_eh_region_ranges): When doing hot/cold partitioning,
	ensure no EH range spans between sections and that landing pads
	are always in the corresponding section.
	(sjlj_size_of_call_site_table, sjlj_output_call_site_table): Adjust
	for crtl->eh.call_site_record being an array rather than scalar.
	(output_one_function_exception_table): New function, copied
	from output_function_exception_table.  Adjust
	dw2_size_of_call_site_table, dw2_output_call_site_table
	callers.  For SECOND section use *C suffixed labels.
	(output_function_exception_table): Call
	output_one_function_exception_table and, when doing hot/cold
	partitioning, also another time for the second section.
	* opts.c: Include except.h.
	(decode_options): Allow -freorder-blocks-and-partition with
	exceptions, unless SJLJ or TARGET_UNWIND_INFO.
	* Makefile.in (opts.o): Depend on $(EXCEPT_H).
	* function.h (struct rtl_eh): Change call_site_record from
	scalar into array of 2 elements.

	* g++.dg/tree-prof/partition1.C: New test.
