DWARF reader: use size_t for DWARF expression length cont.

Browse Source 
A recent change broke 32-bit builds due to an implicit assumption that
size_t == uint64_t. Note that size_t is part of the elfutils
dwarf_getlocation* functions' types.

The previous fix omitted some instances of uint64_t. This commit
updates further functions to consistently use size_t for DWARF
expression lengths and indexes.

	* src/abg-dwarf-reader.cc (eval_last_constant_dwarf_sub_expr):
	Change expr_len argument type to size_t.
	(op_pushes_constant_value): Update ops_len and index argument
	types to size_t. Update next_index argument type to size_t&.
	(op_pushes_non_constant_value): Likewise.
	(op_is_arith_logic): Update expr_len and index argument types
	to size_t. Update next_index argument type to size_t&.
	(op_is_control_flow): Likewise.
