SSA renumber local names; local def-use chains; emit local dead registers annotations using Sudeep's EFLAGS arrays.

Reduced no-op regions, reduced debug output, annotated copies of stack/frame pointer to general registers.

Add displ tag to stack pointer offset annotations to avoid ambiguity in case the same constant offset appears twice in an instruction.

Add SMPFunction::FindAllocPoint method to find end of stack frame allocation when it is done by pushes, e.g. in strpbrk().

Emit annotations for orphan code bytes that were still isUnknown after all other fixups; minor change to ad hoc debugging address.
