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 6c044231 Author: Kenneth Graunke <kenneth@whitecape.org> Date: Sun Feb 2 02:58:42 2014 -0800 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.
