## Summary
Fix assertion failure when evaluating
`__builtin_align_up`/`__builtin_align_down`/`__builtin_is_aligned` with
one-past-end pointers like `&array[size]`.
## Root Cause
`getIndex()` calls `getOffset()` which asserts when `Offset ==
PastEndMark`. This happens for one-past-end element pointers.
## Fix
Check `isElementPastEnd()` before calling `getIndex()`. For past-end
pointers, use `getNumElems()` instead which gives the correct index
value.
## Test
Added test cases in `builtin-align-cxx.cpp` for one-past-end pointer
alignment.
Fixes #178647
