Reland [css-grid] Implement auto-repeat computation

Reland [css-grid] Implement auto-repeat computation

Original CL (1895443002) was reverted because it triggered several
use-of-uninitialized-value errors on Linux WebKit Linux MSan bot. See
crbug.com/589460#c9 for details.

This CL properly initializes the two variables that were used before being
initialized using the appropriate ComputedStyle::initializeXXX() methods.
