Revert of Make the glyph array entries inline. (patchset #10 id:170001 of https://codereview.chromium.org/885903002/)

Reason for revert:
I suspect this is causing the off-by-one character issues that show up in gold.skia.org as of now. All the errors I've seen are on a Win7 bot. Example:

good:

bad:
