Generally, we only check for the presence of compute shaders during
parsing when we find any language (like layout qualifiers) that are
specific to compute shaders, however, it is possible to define an
empty compute shader does not use any language specific to compute
shaders at all and we should fail the compilation anyway. dEQP checks
this.
This patch adds a check for compute shader availability after we have
parsed the source code. At this point we know the effective GLSL version
and also extensions enabled in the shader.
Fixes a subcase of the following dEQP tests:
dEQP-GLES31.functional.debug.negative_coverage.callbacks.shader.compile_compute_shader
dEQP-GLES31.functional.debug.negative_coverage.get_error.shader.compile_compute_shader
dEQP-GLES31.functional.debug.negative_coverage.log.shader.compile_compute_shader
The tests still fail because there is one more subcase that fails that needs
another fix.

One of NIR's invariants is that control flow lists always start and end

This makes calling nir_foo_as_bar a bit safer because we're no longer 100%
trusting in the caller to ensure that it's safe. The caller still needs to
do the right thing but this ensures that we catch invalid casts with an
assert rather than by reading garbage data. The one downside is that we do
use the casts a bit in nir_validate and it's not a validate_assert.

Just generate an __intrinsic_atomic_add with a negated parameter.
Some background on the non-obvious reasons for the the big change to
builtin_builder::call()... this is cribbed from some discussion with
Ilia on mesa-dev.
Why change builtin_builder::call() to allow taking dereferences and
create them here rather than just feeding in the ir_variables directly?
The problem is the neg_data ir_variable node would have to be in two
lists at the same time: the instruction stream and parameters. The
ir_variable node is automatically added to the instruction stream by the
call to make_temp. Restructuring the code so that the ir_variables
could be in parameters then move them to the instruction stream would
have been pretty terrible.
ir_call in the instruction stream has an exec_list that contains
ir_dereference_variable nodes.
The builtin_builder::call method previously took an exec_list of
ir_variables and created a list of ir_dereference_variable. All of the
original users of that method wanted to make a function call using
exactly the set of parameters passed to the built-in function (i.e.,
call __intrinsic_atomic_add using the parameters to atomicAdd). For
these users, the list of ir_variables already existed: the list of
parameters in the built-in function signature.
This new caller doesn't do that. It wants to call a function with a
parameter from the function and a value calculated in the function. So,
I changed builtin_builder::call to take a list that could either be a
list of ir_variable or a list of ir_dereference_variable. In the former
case it behaves just as it previously did. In the latter case, it uses
(and removes from the input list) the ir_dereference_variable nodes
instead of creating new ones.

Previously, we were saving off the last nir_block in a vtn_block before
moving on so that we could find the nir_block again when it came time to
handle phi sources. Unfortunately, NIR's control flow modification code is
inconsistent when it comes to how it splits blocks so the block pointer we
saved off may point to a block somewhere else in the shader by the time we
get around to handling phi sources. In order to get around this, we insert
a nop instruction and use that as the logical end of our block. Since the
control flow manipulation code respects instructions, the nop will keeps
its place like any other instruction and we can easily find the end of our
block when we need it.

While the current CFG code is valid in the case where a switch break also
happens to be a loop continue, it's a bit suboptimal. Since hardware is
capable of handling the continue as a direct jump, it's better to use a
continue instruction when we can than to bother with all of the nasty
switch break lowering.

It is possible that the break block of a switch is actually the continue of
the loop containing the switch. In this case, we need to identify the
break block as a continue and break out of current level of CFG handling.
If we don't, the continue portion of the loop will get handled twice, once
by following after the break and a second time by the loop handling code
handling it explicitly.
