* mips.h: Update documentation of "+s" and "+S".

opcodes/
	* mips-opc.c (mips_builtin_opcodes): Use "+s" for "cins32" and
	"+S" for "cins".
	* mips-dis.c (print_mips_arg): Update "+s" and "+S" comments.
	Combine cases.

gas/
	* config/tc-mips.c (mips_ip): Preserve the real bit number for "+p".
	Require the msb to be <= 31 for "+s".  Check that the size is <= 31
	for both "+s" and "+S".

"+P" Position field of cins/exts aliasing cins32/exts32. Matches if
32 <= pos < 64, otherwise skips to next candidate.
"+Q" Immediate field of seqi/snei. Enforces -512 <= imm < 512.
"+s" Length-minus-one field of cins/exts. Enforces: 0 <= lenm1 < 32.
"+S" Length-minus-one field of cins32/exts32 or cins/exts aliasing
cint32/exts32. Enforces non-negative value and that
pos + lenm1 < 32 or pos + lenm1 < 64 depending whether previous
position field is "+p" or "+P".
"+s" Length-minus-one field of cins32/exts32. Requires msb position
of the field to be <= 31.
"+S" Length-minus-one field of cins/exts. Requires msb position
of the field to be <= 63.

"+a" 8-bit signed offset in bit 6 (OP_*_OFFSET_A)
