[Beignet] [PATCH] improve disassembing load/store IR instructions

[Zhigang Gong]

Homer,

I personally don't think the previous version is not clear. First operator
is destination and the second operator is source.
And use {%x} to indicate it's a value, and without {} indicates it's an
address pointer. It's clear enough for me.

Any strong reason why we need to change to the new style?
