Aleksandr Urakov ceff107778 [ADT] Change the `IntervalMap` alignment assert for x86 MSVC
Summary:
This patch forces the alignment of the `data` field of `IntervalMap`.
It is because x86 MSVC doesn't apply automatically
(without `__declspec(align(...))`) alignments more than 4 bytes,
even if `alignof` has returned so. Consider the example:

https://godbolt.org/z/zIPa_G

Here `alignof` for both `S0` and `S1` returns `8`, but only `S1` is really
aligned on x86. The explanation of this behavior is here:
