[Attributor] UB Attribute now handles all instructions that access
memory through a pointer
Summary: Follow-up on: https://reviews.llvm.org/D71435 We basically use
`checkForAllInstructions` to loop through all the instructions in a
function that access memory through a pointer: load, store, atomicrmw,
atomiccmpxchg Note that we can now use the `getPointerOperand()` that
gets us the pointer operand for an instruction that belongs to the
aforementioned set.
Question: This function returns `nullptr` if the instruction is
`volatile`. Why? Guess:  Because if it is volatile, we don't want to do
any transformation to it.
Another subtle point is that I had to add AtomicRMW, AtomicCmpXchg to
`initializeInformationCache()`. Following `checkAllInstructions()` path,
that seemed the most reasonable place to add it and correct the fact
that these instructions were ignored (they were not in `OpcodeInstMap`
etc.). Is that ok?

[compiler-rt] [netbsd] Define _RTLD_SOURCE to fix build
The TLS base (LWP private pointer) functions are namespaced and hidden
i.e. inside the _RTLD_SOURCE namespace.
