Add (port) performance sensitive randomization
…into no_ranomize_layout_attr
New changes: * RecordFieldOrganizer is an interface that can be used to manipulate a RecordDecl's field order. * RecordFieldOrganizer is a "friend" to the DeclContext (which maintains the linked list) * The Randstruct class is a subclass that performs cache friendly randomization
resolve the identification of the RandomizeLayout attribute to the regression test suite. Without this, running "make clang-test" will result in a failure due to it identifying an attribute but not having it included in ../clang/test/Misc/pragma-attribute-supported-attributes-list.test. This protects against the addition/removal of attributes.
This reverts commit d76e98b.

Looks like a MachinePipeliner algorithm problem found by sanitizer-x86_64-linux-fast. I will backout this test first while investigating the problem to unblock buildbot. ==49637==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x614000002e08 at pc 0x000004364350 bp 0x7ffe228a3bd0 sp 0x7ffe228a3bc8 READ of size 4 at 0x614000002e08 thread T0 #0 0x436434f in llvm::SwingSchedulerDAG::checkValidNodeOrder(llvm::SmallVector<llvm::NodeSet, 8u> const&) const /b/sanitizer-x86_64-linux-fast/build/llvm/lib/CodeGen/MachinePipeliner.cpp:3736:11 #1 0x4342cd0 in llvm::SwingSchedulerDAG::schedule() /b/sanitizer-x86_64-linux-fast/build/llvm/lib/CodeGen/MachinePipeliner.cpp:486:3 #2 0x434042d in llvm::MachinePipeliner::swingModuloScheduler(llvm::MachineLoop&) /b/sanitizer-x86_64-linux-fast/build/llvm/lib/CodeGen/MachinePipeliner.cpp:385:7 #3 0x433eb90 in llvm::MachinePipeliner::runOnMachineFunction(llvm::MachineFunction&) /b/sanitizer-x86_64-linux-fast/build/llvm/lib/CodeGen/MachinePipeliner.cpp:207:5 #4 0x428b7ea in llvm::MachineFunctionPass::runOnFunction(llvm::Function&) /b/sanitizer-x86_64-linux-fast/build/llvm/lib/CodeGen/MachineFunctionPass.cpp:73:13 #5 0x4d1a913 in llvm::FPPassManager::runOnFunction(llvm::Function&) /b/sanitizer-x86_64-linux-fast/build/llvm/lib/IR/LegacyPassManager.cpp:1648:27 #6 0x4d1b192 in llvm::FPPassManager::runOnModule(llvm::Module&) /b/sanitizer-x86_64-linux-fast/build/llvm/lib/IR/LegacyPassManager.cpp:1685:16 #7 0x4d1c06d in runOnModule /b/sanitizer-x86_64-linux-fast/build/llvm/lib/IR/LegacyPassManager.cpp:1752:27 #8 0x4d1c06d in llvm::legacy::PassManagerImpl::run(llvm::Module&) /b/sanitizer-x86_64-linux-fast/build/llvm/lib/IR/LegacyPassManager.cpp:1865 #9 0xa48ca3 in compileModule(char**, llvm::LLVMContext&) /b/sanitizer-x86_64-linux-fast/build/llvm/tools/llc/llc.cpp:611:8 #10 0xa4270f in main /b/sanitizer-x86_64-linux-fast/build/llvm/tools/llc/llc.cpp:365:22 #11 0x7fec902572e0 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x202e0) #12 0x971b69 in _start (/b/sanitizer-x86_64-linux-fast/build/llvm_build_asan/bin/llc+0x971b69) llvm-svn: 363105

SUnit represent a MachineInstr in post-regalloc scheduling but SDNode in pre-regalloc scheduling. when pass -enable-hexagon-sdnode-sched to Hexagon backend with -O1 and above, this may cause an assertion failed. Fixes PR45194. Differential Revision: https://reviews.llvm.org/D76134

https://llvm.org/docs/LangRef.html#llvm-powi-intrinsic The max length of the integer power of `llvm.powi` intrinsic is 32, and the value can be negative. If we use `int32_t` to store this value, `-Val` will underflow when it is `INT32_MIN` The issue was reported in D149033.
