[PATCH] [AArch64] Enhance rematerialization by adding a new API isAsCheapAsAMove in TargetInstroInfo

[Jiangning Liu]

Hi Eric,

OK. Attached are two separate patches.

Hi Qunentin,

I modified the code following your new comments.

Since I don't know how phabaricator will work for two patches uploaded, I'm
simply reply this mail by attached two separate patches. I don't want to
create a new review entry in phabaricator to confuse the people who want to
review the patch.

Thanks,
-Jiangning
