Ported calc-formula-matrix-no-autocalc.diff from ooo-build.

This patch allows formula to be recalculated if it's during matrix
calculation even if the auto recalc flag is OFF.  This is needed
when calculating a formula whose result is a matrix which previously
only calculated the top-left cell when the auto recalc was OFF.
