9b9b1092f0 RISC-V: PR27916, Support mapping symbols.
Similar to ARM/AARCH64, we add mapping symbols in the symbol table,
to mark the start addresses of data and instructions.  The $d means
data, and the $x means instruction.  Then the disassembler uses these
symbols to decide whether we should dump data or instruction.

Consider the mapping-04 test case,
$ cat tmp.s
  .text
  .option norelax
  .option norvc
  .fill 2, 4, 0x1001
  .byte 1
  .word 0
  .balign 8
  add a0, a0, a0
  .fill 5, 2, 0x2002
  add a1, a1, a1
  .data
  .word 0x1             # No need to add mapping symbols.
  .word 0x2

$ riscv64-unknown-elf-as tmp.s -o tmp.o
$ riscv64-unknown-elf-objdump -d tmp.o

Disassembly of section .text:

0000000000000000 <.text>:
   0:   00001001         .word   0x00001001  # Marked $d, .fill directive.
   4:   00001001         .word   0x00001001
   8:   00000001         .word   0x00000001  # .byte + part of .word.
   c:   00               .byte   0x00        # remaining .word.
   d:   00               .byte   0x00        # Marked $d, odd byte of alignment.
   e:   0001             nop                 # Marked $x, nops for alignment.
  10:   00a50533         add     a0,a0,a0
  14:   20022002         .word   0x20022002  # Marked $d, .fill directive.
  18:   20022002         .word   0x20022002
  1c:   2002             .short  0x2002
  1e:   00b585b3         add     a1,a1,a1    # Marked $x.
  22:   0001             nop                 # Section tail alignment.
  24:   00000013         nop

* Use $d and $x to mark the distribution of data and instructions.
  Alignments of code are recognized as instructions, since we usually
  fill nops for them.

* If the alignment have odd bytes, then we cannot just fill the nops
  into the spaces.  We always fill an odd byte 0x00 at the start of
  the spaces.  Therefore, add a $d mapping symbol for the odd byte,
  to tell disassembler that it isn't an instruction.  The behavior
  is same as Arm and Aarch64.

The elf/linux toolchain regressions all passed.  Besides, I also
disable the mapping symbols internally, but use the new objudmp, the
regressions passed, too.  Therefore, the new objudmp should dump
the objects corretly, even if they don't have any mapping symbols.

d1bcae833b ELF: Don't generate unused section symbols
For ELF targets, section symbols are required only for relocations.
With -ffunction-sections -fdata-sections, there can be many unused
section symbols.  Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are

With unused section symbols   : 39411698 bytes
Without unused section symbols: 39227002 bytes

The unused section symbols in libstdc++.a occupy more than 180 KB.

Add BSF_SECTION_SYM_USED to indicate if a section symbol should be
included in the symbol table.  The BSF_SECTION_SYM_USED should be set
if the section symbol is used for relocation or the section symbol is
always included in the symbol table.

Add keep_unused_section_symbols to bfd_target to indicate if unused
section symbols should be kept.  If TARGET_KEEP_UNUSED_SECTION_SYMBOLS
is defined as FALSE, unused ection symbols will be removed.

Tested on Linux/x86.  Other ELF backends need to:

1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE.
2. Mark used section symbols in assembler backend.
3. Remove unused section symbols from expected assembler and linker
outputs.
