Fix sfence, lfence, mfence, and clflush to be able to be selected when AVX is enabled. Fix monitor and mwait to require SSE3 or AVX, previously they worked even if SSE3 was disabled. Make prefetch instructions not set the execution domain since they don't use XMM registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147409 91177308-0d34-0410-b5e6-96231b3b80d8

Partition use lists so defs always come before uses. This makes it possible to speed up def_iterator by stopping at the first use. This makes def_empty() and getUniqueVRegDef() much faster when there are many uses. In a +Asserts build, LiveVariables is 100x faster in one case because getVRegDef() has an assertion that would scan to the end of a def_iterator chain. Spill weight calculation is significantly faster (300x in one case) because isTriviallyReMaterializable() calls MRI->isConstantPhysReg(%RIP) which calls def_empty(%RIP). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161634 91177308-0d34-0410-b5e6-96231b3b80d8
