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.

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.
