llvmpipe: fix denorm handling for r11g11b10_float format when blending

The code re-enabling denorms for small float formats did not recognize
this format due to format handling hacks (mainly, the lp_type doesn't have
the floating bit set).

i965: Duplicate gen7_atoms to gen8_atoms.

It's going to diverge significantly.  Starting out with a copy allows
future patches to change atoms one by one.

i965: Bump generation assertions on workaround flushes.

I haven't investigated whether these are necessary on Broadwell or not,
but for paranoia's sake, we may as well continue doing them for now.

i965: Update SF, SBE, and RASTER state for Broadwell.

The attribute override portion of 3DSTATE_SBE was split out into
3DSTATE_SBE_SWIZ; various bits of 3DSTATE_SF were split out into
3DSTATE_RASTER.

v2: Set Force URB Read Offset bit.  Eventually the URB read offset
    should be set in 3DSTATE_VS, but that will require some refactoring.

v3: Rebase on viewport array changes.

v4: Improve comments about URB read length/offset overrides.

i965: Replace DEPTH_STENCIL_STATE with Gen8's 3DSTATE_WM_DEPTH_STENCIL.

v2: Use stencil->_WriteEnabled instead of setting
    GEN8_WM_DS_STENCIL_BUFFER_WRITE_ENABLE twice (suggested by Eric).

v3: Mask stencil->WriteMask and stencil->ValueMask with 0xff.  The field
    is only 8-bits, so we'd trip the new SET_FIELD assertion when core
    Mesa gave us a value like 0xFFFFFFFF.  The Gen7 code uses structure
    field widths to implicitly do this truncation.  Fixes Piglit tests.

v4: Use uint32_t for dw1/dw2, not uint8_t.  Worst. Typo. Ever.

i965: Add the new 3DSTATE_PS_BLEND state packet.

v2: Only set GEN8_PS_BLEND_HAS_WRITEABLE_RT if color buffer writes are
    enabled (caught by Eric Anholt).

v3: Set non-blending flags (writeable RT, alpha test, alpha to coverage)
    for integer formats too.  +14 Piglits.

i965: Rework 3DSTATE_VS for Broadwell.

v2: Remove incorrect MOCS shifts; rename urb_entry_write_offset to
    urb_entry_output_offset to closer match the documentation.

v3: Only emit a non-zero constant buffer read length when active.

v4: Add missing binding table counts (caught by Eric).

v5: Rebase on Paul Berry's changes to CurrentVertexProgram.

v6: Drop bogus SBE read length/offset field code.  We were programming
    the wrong values, and our 3DSTATE_SBE code overrides any value we
    put here anyway with the correct one.

i965: Update 3DSTATE_PS, 3DSTATE_WM, and add 3DSTATE_PS_EXTRA.

v2: Fix setting of GEN8_PSX_ATTRIBUTE_ENABLE after rebases.

v3: Add missing binding table entry counts.  Don't worry about alpha
    testing or alpha to coverage when setting the "Kill Pixel" bit;
    those are specified in 3DSTATE_PS_BLEND (caught by Eric Anholt).
    Drop unused _NEW_BUFFERS.  Tidy comments.

v3: Add a perf_debug for missing MOCS setup, requested by Eric.

v4: Fix buffer sizes.  The value, specified at bit 12 and up, is

v4: Program 3DSTATE_SGVS even in the no-elements case so gl_VertexID

i965: Update SOL state for Broadwell.

Unlike on Gen7, we can directly set the offset via the state packet.
We also -have- to: the kernel SOL reset code won't work anymore.

v2: Fix copy and paste mistake in buffer stride setup; drop stale
    comment (caught by Eric Anholt).  Add a perf_debug for missing
    MOCS setup.

v3: Rebase on Paul Berry's changes to CurrentVertexProgram.

v4: Fix SO Write Offset handling.  We need to set bits 20 and 21 so the
    hardware both loads and saves the offset.  There's also a
    restriction that 3DSTATE_SO_BUFFER can only be programmed once per
    buffer between primitives, so the "reset to zero" code needed
    reworking.  Fixes most of the transform feedback Piglit tests.

i965: Rework SURFACE_STATE entries for Broadwell.

v2: Add missing SCS setting in gen8_emit_buffer_surface_state (caught by

v3: Use stored QPitch rather than recomputing it.

v4: Shift QPitch by 2 when setting it in the packet; bits 14:0 store
    bits 16:2 of the actual value (fixes myriads of cube and array
    texturing tests).  Also, only enable cube face bits for cubemaps
    (matches Chris Forbes' commit on master).  Port to use offset64.

v5: s/gl_format/mesa_format/g

v6: Fix DW5 of renderbuffer state, which neglected to subtract
    irb->mt->first_level.  Use vertical_alignment() rather than

    large switch statement (all caught/suggested by Eric).
