1) Changed gather and scatter intrinsics. Now they are aligned with GCC built-ins. There is no more non-masked form. Masked intrinsic receives -1 if all lanes are executed. 2) I changed the function that works with intrinsics inside X86ISelLowering.cpp. I put all intrinsics in one table. I did it for INTRINSICS_W_CHAIN and plan to put all intrinsics from WO_CHAIN set to the same table in order to avoid the long-long "switch". (I wanted to use static map initialization that allowed by C++11 but I wasn't able to compile it on VS2012). 3) I added gather/scatter prefetch intrinsics. 4) I fixed MRMm encoding for masked instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208522 91177308-0d34-0410-b5e6-96231b3b80d8
