i965/gen5,6: Fix hang when emitting hiz buffer without stencil buffer
When emitting either a hiz or stencil buffer, the 'separate stencil
enable' and 'hiz enable' bits are set in 3DSTATE_DEPTH_BUFFER. Therefore
we must emit both 3DSTATE_HIER_DEPTH_BUFFER and 3DSTATE_STENCIL_BUFFER.
Even if there is no stencil buffer, 3DSTATE_STENCIL_BUFFER must be
emitted; failure to do so causes a hang on gen5 and a stall on gen6.
This also fixes a silly, obvious segfault that occured when a hiz buffer
xor separate stencil buffer existed.
Fixes the piglit tests below on Gen5 when hiz and separate stencil are
manually enabled:
fbo-alphatest-nocolor
fbo-depth-sample-compare
fbo
hiz-depth-read-fbo-d24-s0
hiz-depth-stencil-test-fbo-d24-s0
hiz-depth-test-fbo-d24-s0
hiz-stencil-read-fbo-d0-s8
hiz-stencil-test-fbo-d0-s8
fbo-missing-attachment-clear
fbo-clear-formats
fbo-depth-*
Changes piglit test result from crash to fail:
hiz-depth-stencil-test-fbo-d0-s8
