[cfe-dev] [3.6 Release] Bugfixes in Masked Load/Store

[Demikhovsky, Elena]

Hi Hans,

I fixed 2 bugs in the trunk branch related to Masked Load / Store.
Since these intrinsics are generated by Loop Vectorizer on AVX2, a wrong code may be generated. One of the bugs was detected while gcc benchmark testing.
http://llvm.org/bugs/show_bug.cgi?id=22225

I think that the bugs should be fixed in 3.6.
I have 2 options
(1) promote changes of revisions 226791 and 226808 from trunk to 3.6
(2) disable the Masked Load / Store support for AVX2 in 3.6 

Please let me know what do you think?

-  Elena
