meta: Refactor handling of GL_MULTISAMPLE.

In commit 055093e (meta: remove call to _meta_in_progress(), fix
multisample enable/disable), we created a meta_set_enable() function
that could be used by meta ops to enable and disable GL_MULTISAMPLE
even when the GLES API was in use (the GLES API doesn't support
GL_MULTISAMPLE; it behaves as if it is always enabled).  This created
some unfortunate code duplication between meta_set_enable() and the
existing _mesa_set_enable() function.

This patch eliminates the duplication by creating a
_mesa_set_multisample() function, which is used by both meta ops and
_mesa_set_enable() to enable/disable GL_MULTISAMPLE.

i965: Fix out-of-order sampler unit usage in ARB fragment programs.

ARB fragment programs use texture unit numbers directly, unlike GLSL
which has an extra indirection.  If a fragment program only uses one
texture assigned to GL_TEXTURE1, SamplersUsed will only contain a single
bit, which would make us only upload a single surface/sampler state
entry.  However, it needs to be the second entry.

Using _mesa_fls() instead of _mesa_bitcount() solves this.  For ARB
programs, this makes num_samplers the ID of the highest texture unit
used.  Since GLSL uses consecutive integers assigned by the linker,
_mesa_fls() should give the same result as _mesa_bitcount()..

Fixes a regression since 85e8e9e000732908b259a7e2cbc1724a1be2d447,

NOTE: This is a candidate for stable release branches.

Acked-by: Eric Anholt <eric@anholt.net>

i965/blorp: Reduce alignment restrictions for stencil blits.

Previously, we aligned all stencil blit operations to multiples of the
size of a tile, since stencil buffers use W-tiling, and blorp has to
approximate this by configuring the 3D pipeline for Y-tiling and
swizzling coordinates.

However, this was unnecessarily conservative; it turns out that the
differences between W-tiling and Y-tiling are confined to 32-byte
sub-tiles within the 4k tiling pattern; the layout of these 32-byte
sub-tiles within the larger 4k tile is the same (8 sub-tiles across by
16 sub-tiles down, in column-major order).  Therefore we only need to
align stencil blit operations to multiples of the sub-tile size.

Note: although the performance improvement of this change is probably
quite small, the fact that W-tiling and Y-tiling formats only differ
within 32-byte sub-tiles will be essential in a future patch to ensure
that stencil blits work correctly between parts of the miptree other
than level/layer 0.  Making this change provides handy documentation
(and validation) of this fact.

NOTE: This is a candidate for stable release branches.
