Use FX_SAFE_UINT32 on CPDF_ToUnicodeMap::Load
m_Map maps to unsigned integer, but m_MultiCharBuf.GetLength() returns an integer. There will be integer overflow if the length is big, and UBSAN will complain. Thus, using FX_SAFE_UINT32. Replacing with uint32 would work as well: the point is to consider the length as uint instead of int. BUG=chromium:652232 Review-Url: https://codereview.chromium.org/2393573002
