[PATCH v3 0/2] MR7312: msvcp: Avoid explicitly aligning fpos_mbstatet.

[Jacek Caban (＠jacek)]

Based on Piotr's findings.

On MSVC i386 targets, structs requiring alignment greater than 4 are never passed by value.
Clang follows the same behavior in MSVC mode (see [1] for details and [2] for a follow-up
that applies this logic when fields, not necessarily the entire struct, are aligned).

A number of ios functions take fpos_mbstatet as an argument and expect it to be passed by value.
