8af9de0a38 spirv: Change vtn_null_constant() to use vtn_type
This is a preparation to handle OpConstantNull for pointers, we'll use
the vtn_type to get to the address format and then the appropriate
representation of NULL pointer.

v2: Move rest of body to use vtn_type. (Jason)

Instead of setting the glsl types of the pointers for each resource,
set the nir_address_format, from which we can derive the glsl_type,
and in the future the bit pattern representing a NULL pointer.

1fb6630636 spirv: Properly handle SpvOpAtomicCompareExchangeWeak
The code was handling the Weak variant in some cases, but missing
others, e.g. the get_deref_nir_atomic_op.  Add all the missing cases
with the same behavior of the non-Weak SpvOpAtomicCompareExchange.

Note that the Weak variant is basically an alias, as SPIR-V 1.3,
Revision 7 says

    "OpAtomicCompareExchangeWeak

    Deprecated (use OpAtomicCompareExchange).

    Has the same semantics as OpAtomicCompareExchange."

cbfe31ccbe Revert "nir: const nir_call_instr::callee"
This reverts commit db57db5317.  When
building IR, nothing is really immutable and, since C has no concept of
constness propagating beyond the first pointer, we have to be vary
careful with how we use it.  To just throw const into a function like
this is a lie.

Instead, we should just drop the unneeded const in spirv_to_nir which
this commit does along with the revert.

c95afe56a8 nir/spirv: handle kernel function parameters
the idea here is to generate an entry point stub function wrapping around the
actual kernel function and turn all parameters into shader inputs with byte
addressing instead of vec4.

This gives us several advantages:
1. calling kernel functions doesn't differ from calling any other function
2. CL inputs match uniforms in most ways and we can just take advantage of most
   of nir_lower_io

v2: move code into a seperate function
v3: verify the entry point got a name
    fix minor typo
v4: make vtn_emit_kernel_entry_point_wrapper take the old entry point as an arg
