Fix a bug in nested context code that occured when calling a function nested in
...

For the outermost function needing a context frame, use the address of that
...
frame as the nest argument instead of the address of a single-element list
containing only that frame address.
This saves some stack space and reduces memory accesses.

Add some alignment info where LLVM might otherwise be more pessimistic.
...
In particular, %.nest_arg is always aligned even though it's bitcast from i8*.
Pointers in vtables are also guaranteed to be stored at aligned addresses.
