Add NOP after store operation

[Michael Trimarchi]

Hi all,
my intention is to add a fixed number of NOP operation after a str in 
arm. I have a problem width the memory bus and I must solve this problem 
width a delay in the store operation. I would change the md_assemble 
function to add nop if the opcode is related to a store. I think that I 
must change the tc-arm.c file and the read.c in the gas directory. Is it 
correct?
