Herb Derby b70a030066 Guard against overflow in blur code. 
This fuzz creates a blur that has w = 1 and h = 2^31 - epsilon.
And a filter sigma of 360. This causes the intermediate
buffer size > 2^31. This causes the multiply in the following
code SkMaskBlurFilter.cpp:1023:

  tmpStart + tmpW * tmpH

to overflow. Because tmpW = source height, which is near 2^31,
and tmpH is about 3*360.

Cause the blur to fail if the intermediate buffer is > INT_MAX.
