Previously, copy propagation would cause bitcast_f2u(abs(float)) to
be performed in a single step, but the application of source modifiers
(abs, neg) happens after type conversion, leading to incorrect results.
That is, for bitcast_f2u(abs(float)) we would in fact generate code to
do abs(bitcast_f2u(float)).
For example, whereas bitcast_f2u(abs(float)) might result in a register
argument such as
(abs)g2.2<0,1,0>UD
v2: Set interfered = true and break in register_coalesce instead of
returning false.

(cherry picked from commit 9c48ae751a)
Necessary to avoid combining a bitcast and a modifier into a single
operation. Otherwise if safe, the MOV should be removed by
copy-propagation or register coalescing.
With this and the next patch, there are only four changes in shader-db:
all a single extra instruction. The code does something like
mov a.w, -b.x
and copy propagation doesn't work because it only handles no-op
swizzles. Seems acceptable, given the known limitation of our copy
propagation.

NOTE: The bit of strangeness with the version of visit_field without the
record_type poitner is because that method is pure virtual in the base
class. The original implementation of the class did this to ensure
derived classes remembered to implement that flavor. Now they can
implement either flavor but not both. I don't know a C++ way to enforce
that.

struct S {

s.s1.v would get record_type = S (because s1.v is the first non-record
field in S), and s.s2.v would get record_type = S1. s.s1.f and s.s2.f
would get record_type = NULL becuase they aren't the first field of

This patch fixes a case of framebuffer blitting with renderbuffer
as color attachment and GL_LINEAR filter. Meta implementation of
glBlitFrambuffer() converts source color buffer to a texture and
uses it to do the scaled blitting in to destination buffer. Using
the exact source rectangle to create the texture does incorrect
linear filtering along the edges. This patch makes the changes to
extend the texture edges by one pixel in x, y directions. This
ensures correct linear filtering.
It fixes failing piglit fbo-attachments-blit-scaled-linear test.

(cherry picked from commit 14ee790df7)
Previously we would emit a warning for empty declarations like
float;
We would also emit the same warning for things 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.
It really seems like this should be an error. I'll bet that 100% of the
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:
0:12(11): warning: empty declaration with precision qualifier, to set the default precision, use `precision lowp float;'
0:13(12): warning: empty declaration with precision qualifier, to set the default precision, use `precision mediump int;'

Since disabling denorms in draw_vbo() we require the util_cpu_caps to be
initialized there. Hence add another util_cpu_detect() call in
draw_create_context() which should ensure this.
(There is another call in draw_get_option_use_llvm() which only gets called
with x86 (not x86_64) but calling it always there wouldn't help since it most
likely wouldn't get called when compiling without llvm, so leave it alone
there.)
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=66806.
(Because util_cpu_caps wasn't initialized when first calling util_fpstate_get()
hence it returning zero, but it would later get initialized by rtasm translate
code hence when draw call returned it unmasked all exceptions by calling
util_fpstate_set(). This was happening only with DRAW_USE_LLVM=0 or not
compiling with llvm, otherwise the llvm init code was calling it on time too.)

GLSL ES does not allow unsized arrays, and GLSL ES 1.00 does not allow
array initializers. However, GLSL ES 3.00 allows array initializers,
and the initializer can explicitly size the array. The specification
even includes some examples of this:
float x[] = float[2] (1.0, 2.0); // declares an array of size 2
float y[] = float[] (1.0, 2.0, 3.0); // declares an array of size 3
float a[5];
float b[] = a;
Move the unsized array check to after the initializer has been
processed. If the array is still unsized, generate the error. This
should have no effect in GLSL ES 1.00 because, as previously mentioned,
array initializers are not allowed.
