Reviewed by Kent Tamura.

Unlike gcc and clang, MSVC pads each consecutive member variables of the same type in bitfields. e.g. if you have:
sturct AB {
unsigned m_1 : 31;
bool m_2 : 1;
}
then MSVC pads m_1 and allocates sizeof(unsigned) * 2 for AB whereas gcc and clang only allocate
sizeof(unsigned) * 1 for AB.

Fixed the bug by packing all bitfields in InlineBox into InlineBoxBitfields and always using either unsigned or int.
