```
x86_64: add frame indices

This allows abstract references to the stack frame which enables:
 * deferred frame layout until after the function has been processed
 * frame compaction (sorting by alignment)
 * being able to overalign the stack
 * references that change based on an overaligned stack
 * moving callee saved spills to the usual part (smaller code size)
 * shared call frame (avoids stack adjustments before and after calls)

```
