xtensa: use property tables for correct disassembly
xtensa disassembler does not use information from the .xt.prop sections
to switch between code/data disassembly in text sections. This may
result in incorrect disassembly when data is interpreted as code and
disassembler loses synchronization with instruction stream. Use .xt.prop
section information to correctly interpret code and data and synchronize
with instruction stream.

bfd/
* elf32-xtensa.c (xtensa_read_table_entries): Make global.
(compute_fill_extra_space): Drop declaration. Rename function to
xtensa_compute_fill_extra_space.
(compute_ebb_actions, remove_dead_literal): Update references to
compute_fill_extra_space.
include/
* elf/xtensa.h (xtensa_read_table_entries)
(xtensa_compute_fill_extra_space): New declarations.
opcodes/
* xtensa-dis.c (bfd.h, elf/xtensa.h): New includes.
(dis_private): Add new fields for property section tracking.
(xtensa_coalesce_insn_tables, xtensa_find_table_entry)
(xtensa_instruction_fits): New functions.
(fetch_data): Bump minimal fetch size to 4.
(print_insn_xtensa): Make struct dis_private static.
Load and prepare property table on section change.
Don't disassemble literals. Don't disassemble instructions that
cross property table boundaries.
