Jack Carter 97265a4889 Mips assembler: .set reorder support 
Mips have delayslots for certain instructions 
like jumps and branches. These are instructions 
that follow the branch or jump and are executed
before the jump or branch is completed.

Early Mips compilers could not cope with delayslots
and left them up to the assembler. The assembler would
fill the delayslots with the appropriate instruction,
usually just a nop to allow correct runtime behavior.

The default behavior for this is set with .set reorder.
To tell the assembler that you don't want it to mess with
the delayslot one used .set noreorder.

For backwards compatibility we need to support
.set reorder and have it be the default behavior in the 
assembler.

Our support for it is to insert a NOP directly after an
instruction with a delayslot when in .set reorder mode.
