[PATCH] [MIPS] Fix operands for microMIPS SW16, SH16 and SB16

[Moore, Catherine]

Hi Richard,

This patch fixes a problem with the SW16, SH16 and SB16 microMIPS instructions. 
 GCC is incorrectly calculating the length of these instructions if $16 is used 
as the source operand.  The incorrect length calculation can cause a 32-bit 
instruction to be placed in a short delay slot.  The assembler does detect this 
and issues a warning.

This patch changes the allowable registers for the short store instructions to 
$0, $2-$7, and $17.

Okay to install?  Okay to install for 4.9?

Thanks,
Catherine
