mesa: Set query->EverBound in glQueryCounter().

glIsQuery is supposed to return false for names returned by glGenQueries
until their first use.  BeginQuery is a use, but QueryCounter is also a
use.

From the ARB_timer_query spec:
"A timer query object is created with the command

      void QueryCounter(uint id, enum target);

 [...] If <id> is an unused query object name, the
 name is marked as used [...]"

Fixes Piglit's spec/ARB_timer_query/query-lifetime.

We never noticed that this field was uninitialized because it is only

But it's silly to have it around anyway because &brw->ctx is
equivalent.

i965: Allow C++ type safety in the use of enum brw_urb_write_flags.

(From a suggestion by Francisco Jerez)

If an enum represents a bitfield of flags, e.g.:

enum E {
  A = 1,
  B = 2,
  C = 4,
  D = 8,
};

then C++ normally prohibits statements like this:

enum E x = A | B;

because A and B are implicitly converted to ints before OR-ing them,
and an int can't be stored in an enum without a type cast.  C, on the
other hand, allows an int to be implicitly converted to an enum
without casting.

In the past we've dealt with this situation by storing flag bitfields
as ints.  This avoids ugly casting at the expense of some type safety
that C++ would normally have offered (e.g. we get no warning if we
accidentally use the wrong enum type).

However, we can get the best of both worlds if we override the |
operator.  The ugly casting is confined to the operator overload, and
we still get the benefit of C++ making sure we don't use the wrong
enum type.

v2: Remove unnecessary comment and unnecessary use of "enum" keyword.
Use static_cast.

i965/vs: Use a fixed set of register classes.

Arrays, structures, and matrices use large VGRFs of arbitrary sizes.
However, split_virtual_grfs() breaks those down into VGRFs of size 1.

For reference, commit 5d90b988791e51cfb6413109271ad102fd7a304c is the
analogous change to the FS backend.

i965/vs: Expose the payload registers to the register allocator.

For now, nothing else can get allocated over them.  That may change at
some point in the future.

This also means that base_reg_count can be computed without knowing the
number of registers used for the payload, which is required if we want
to allocate the register set once at context creation time.

See commit 551e1cd44f6857f7e29ea4c8f892da5a97844377, which implemented
virtually identical code in the FS backend.

i965/vs: Allocate register set once at context creation.

Now that we use a fixed set of register classes, we can set up the
register set and conflict graphs once, at context creation, rather than
on every VS compile.  This is obviously less expensive, and also what
we already do in the FS backend.
