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			`define i32 @exchange_and_add(i32* %mem, i32 %val) nounwind {`

Convert more tests over to the new atomic instructions. I did not convert Atomics-32.ll and Atomics-64.ll by hand; the diff is autoupgrade output. The wmb test is gone because there isn't any way to express wmb with the new atomic instructions; if someone really needs a non-asm way to write a wmb on Alpha, a platform-specific intrisic could be added. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140566 91177308-0d34-0410-b5e6-96231b3b80d8 2011-09-26 21:30:17 +00:00			`%tmp = atomicrmw add i32* %mem, i32 %val monotonic`
