I have an alternative suggestion :)
Instead of trying to use STIX Math as a text font, let's leave it doing 
what it does best and instead use a matching Times-clone for the text. 
This is what I would recommend:

\setmainfont[
    Extension=.otf,
    UprightFont=*-regular,
    ItalicFont=*-italic,
    BoldFont=*-bold,
    BoldItalicFont=*-bolditalic,
    Numbers=OldStyle,
    Mapping=tex-text
  ]{texgyretermes}
\setmathfont{XITS Math}

(If you install TeX Gyre Terms in your system then you don't need the 
long-winded \setmainfont options.)

When you think about it, it doesn't exactly make sense to try and use 
STIX as a text font -- the bold and italic letters and kerning will 
have been designed for maths use, not text. And while they *can* 
function acceptably in text, TeX Gyre Termes is specifically a text 
font and has excellent glyph coverage.

Hope this helps,
Will
