glsl: rewrite glsl_type::record_key_hash() to avoid buffer overflow

This should be more efficient than the previous snprintf() solution.
But more importantly, it avoids a buffer overflow bug that could result
in crashes or unpredictable results when processing very large interface
blocks.

For the app in question, key->length = 103 for some interfaces.  The check
if size >= sizeof(hash_key) was insufficient to prevent overflows of the
hash_key[128] array because it didn't account for the terminating zero.
In this case, this caused the call to hash_table_string_hash() to return
different results for identical inputs, and then shader linking failed.

This new solution also takes all structure fields into account instead
of just the first 15 when sizeof(pointer)==8.

i965: Replace guess_execution_size with something simpler.

guess_execution_size() does two things:

   1. Cope with small destination registers.
   2. Cope with SIMD8 vs SIMD16 mode.

This patch replaces the first with a simple if block in brw_set_dest: if
the destination register width is less than 8, you probably want the
execution size to match.  (I didn't put this in the 3src block because
it doesn't seem to matter.)

Since only the FS compiler cares about SIMD16 mode, it's easy to just
set the default execution size there.

This pattern was already been proven in the Gen8+ generator, but we
didn't port it back to the existing generator when we combined the two.

This is based on a patch from Ken from about a year ago. I've rebased it

it was only used in order to make it pick a tightly-packed qpitch

be necessary after the next patch because it will automatically pick a

mipmaps it isn't possible to support the case where there are mipmaps
because in that case the layout is very different.

It could be good to make a similar change for Gen8 if we also change

i965/fs: Use the source type when looking for UD negations in copy prop

There can be problems with floats and conditional modifiers when
copy-propagating a negated UD source.  The problem arises when a source
modifier is applied to a UD value.  In this case, a 33-bit representation
is internally used.  If you do the following:

   1: mov foo:UD 7U
   2: mov bar:UD -foo:UD
   3: mov out:F bar:UD

the out register will have the value (float)(unt32_t)-7 which is some very
large floating-point number.  However, if we allow copy-propagation of the
second mov, we get

   1: mov foo:UD 7U
   3: mov out:f -bar:UD

and, since the negation is computed in 33-bits, we get a value of -7.0f
which is clearly not the same.  This is a similar problem if the
instruction has a conditional modifier where the 33-bit value is used in
the comparison and not the 32-bit version.

Previously, we checked the source to be copied for the negate and then
checked the source being propagated to for the type.  This isn't quite what
we want because we are really just looking for negated UD sources.  A check
later in the file ensures that both ends of the propagate have the right
type so it works.  However, if we relax the restriction that both ends of
