rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the target indep prefetch change. As usual, updating the testsuite is a PITA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133337 91177308-0d34-0410-b5e6-96231b3b80d8 2011-06-18 06:05:24 +00:00			`call void @llvm.memset.p0i8.i32(i8* %ptr, i8 undef, i32 512, i32 1, i1 false)`
