PR analyzer/104560 reports various false positives from -Wanalyzer-free-of-non-heap seen with rdma-core, on what's effectively: free (&ptr->field) where in this case "field" is the first element of its struct, and thus &ptr->field == ptr, and could be on the heap. The root cause is due to malloc_state_machine::on_stmt making "LHS = &EXPR;" transition LHS from start to non_heap when EXPR is not a MEM_REF; this assumption doesn't hold for the above case. This patch eliminates that state transition, instead relying on malloc_state_machine::get_default_state to detect regions known to not be on the heap. Doing so fixes the false positive, but eliminates some events relating to free-of-alloca identifying the alloca, so the patch also reworks free_of_non_heap to capture which region has been freed, adding region creation events to diagnostic paths, so that the alloca calls can be identified, and using the memory space of the region for more precise wording of the diagnostic. The improvement to malloc_state_machine::get_default_state also means we now detect attempts to free VLAs, functions and code labels. In doing so I spotted that I wasn't adding region creation events for regions for global variables, and for cases where an allocation is the last stmt within its basic block, so the patch also fixes these issues. Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
