glsl: Fix incorrect pattern matching in ir_set_program_inouts

In commit 8fc41df (glsl: Modify ir_set_program_inouts to handle
geometry shaders), when attempting to pattern match the "foo" part of
expressions such as:

   foo[i][j]
   foo[i]

I incorrectly called as_dereference_variable() on the subexpression
foo[i] instead of foo.  As a result, the pattern never matched, so
ir_set_program_inouts would fall back on marking the entire variable
as used, rather than just the portion indexed by the array.

This didn't result in incorrect behaviour, but it could have resulted
in inefficiency by causing the back-end to allocate resources for
unused parts of an input or output array.

glsl: Emit better warnings for things that look like default precision statements

Previously we would emit a warning for empty declarations like

highp float;

However, this second case is most likely the application trying to set
the default precision.  This makes the compiler generate a stronger
warning with some suggestion of a fix.

time someone writes 'highp float;' the actually meant 'precision highp
float;'.  Alas, both AMD and NVIDIA accept this syntax, and the spec
doesn't explicitly forbid it.

This makes piglit's precision-05.vert generate the following warnings:

i965/fs: Consider predicated SEL instructions as whole variable writes.

The instruction

   (+f0.0) SEL dst, src0, src1

will write either src0 or src1 to dst, depending on the predicate.
Unlike most predicated instructions, it always writes to dst.

fs_inst::is_partial_write() is supposed to return true if the whole
register is guaranteed to be written.  The !inst->predicated check makes
sense for most instructions, which might not write the whole register,
but SEL is a special case.

This caused live interval analysis to ignore the destination of
predicated SEL instructions when computing "def" information.

Requires the previous commit to avoid regressions.

gallivm: use texture target from shader instead of static state for size query

d3d10 has no notion of distinct array resources neither at the resource nor
sampler view level. However, shader dcl of resources certainly has, and
d3d10 expects resinfo to return the values according to that - in particular
a resource might have been a 1d texture with some array layers, then the
sampler view might have only used 1 layer so it can be accessed both as 1d
or 1d array texture (I think - the former definitely works). resinfo of a
resource decleared as array needs to return number of array layers but
non-array resource needs to return 0 (and not 1). Hence fix this by passing
the target from the shader decl to emit_size_query and use that (in case of
OpenGL the target will come from the instruction itself).
Could probably do the same for actual sampling, though it may not matter there
(as the bogus components will essentially get clamped away), possibly could
wreak havoc though if it REALLY doesn't match (which is of course an error
but still).
