[PATCH bfin] 64bit constant folding

[Jie Zhang]

This patch tries to make Blackfin gas assemble such instruction:

R0 = (19088743 * 19088743 / 19088743 / 19088743)

Blackfin gas has its own expression parsing routines. While other 
targets are able to do such calculation, Blackfin gas can not without 
this patch.

Committed.
