<pre>Kalyan and Tapani confirmed that my patch fixes the test on 64-bit Sandybridge.
I confirmed the fix on 64-bit Ivybridge.
Still waiting for a QA update on 32-bit Sandybridge with a modern Chromium.
Patch is committed to Mesa master as

i965: Fix segfault in WebGL Conformance on Ivybridge
Fixes regression of WebGL Conformance test texture-size-limit [1] on
Ivybridge Mobile GT2 0x0166 with Google Chrome R38.
Regression introduced by
commit 6c044231535b93c5d16404528946cad618d96bd9

i965: Bump GL_MAX_CUBE_MAP_TEXTURE_SIZE to 8192.
The test regressed because the pointer offset arithmetic in
intel_miptree_map_gtt() overflows for large textures. The pointer
arithmetic is not 64-bit safe.
