RFC: Introduce DW_OP_LLVM_memory to describe variables in memory with dbg.value
Debug info today handles two cases reasonably well:
1. At -O0, dbg.declare does a good job describing variables that live at
some known stack offset
2. With optimizations, variables promoted to SSA can be described with
dbg.value
This leaves behind a large hole in our optimized debug info: variables that
cannot be promoted, typically because they are address-taken. This is
