i965: Support instruction compaction between control flow.

Reviewed-by: Paul Berry <stereotype441@gmail.com>

i965: Add support for instruction compaction.

This reduces program size by using some smaller encodings for common bit
patterns in the Gen ISA, with the hope of making programs fit in the
instruction cache better.

v2: Use larger bitshifts for the uncompressed field setups, in line with the
    way it's described in the spec.  Consistently name a brw_compile "p" like
    all other code.  Add a couple more tests.  Consistently call things
    "compacted" not "compressed" (which is a different feature).  Drop the
    explicit check for not compacting SENDs, which is unjustified and already
    implied by our lack of support for immediate values.

i965: Prepare the break/cont uip/jip setting for compacted instructions.

The first cut at instruction compaction won't compact things that
would change control flow jump distances, but we do need to still be
able to walk the instruction stream, which involves jumping by 8 or 16
bytes between instructions.

i965: Move program dump to a helper function in brw_eu.c.

It's going to get more complicated when we do instruction compaction.  This
also introduces putting the program offset in the output.

v2: Use next_insn_offset in brw_get_program(), too.

i965: Make a linkable library for the contents of i965_dri.so.

To do unit testing of i965, we want to be able to link against the
driver's symbols and prod them.  If we don't have a separate lib from
our loadable module, libtool gets super whiny.

dri: Reuse dri_test.c for stub glapi symbols for unit testing.

i965: Clear brw_compile on setup.

I noticed in valgrind that p->single_program_flow was used while
uninitialized.  Everything else zeroed out brw_compile, but this is better
API.

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.
