[Bug gas/4448] New: overstrict check for powerpc lswi

[doko at debian dot org]

[ forwarded from http://bugs.debian.org/421799 ]

seen with 20070426 CVS

The opcode check for the lswi instruction is overstrict:

| $ cat test.S
|         lswi 5,24,0
| $ as test.S 
| test.S: Assembler messages:
| test.S:1: Error: operand out of range (0 is not between 1 and 32)

The IBM reference say:
| lswi   RT, RA, NB
| NB is the byte count.
| N is NB, which is the number of bytes to load. If NB is 0, then N is 32.
