Add .nop assembler directive
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits
SIZE bytes filled with no-op instructions. SIZE is absolute expression.
The optional CONTROL byte controls how no-op instructions should be
generated. If the comma and @var{control} are omitted, CONTROL is
assumed to be zero.
For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size
limit of a single no-op instruction. The valid values of CONTROL byte
are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode,
between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit
is set to the maximum supported size.
2 new relax states, rs_space_nop and rs_fill_nop, are added to enum
_relax_state, which are similar to rs_space and rs_fill, respectively,
but they fill with no-op instructions, instead of a single byte. A
target backend must override the default md_generate_nops to generate
proper no-op instructions. Otherwise, an error of unimplemented .nop
directive will be issued whenever .nop directive is used.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.
