Vulkan: Atomic counter buffer support
Vulkan doesn't treat atomic counters especially, and they are emulated
with atomic access to storage buffers.
A single atomic counter buffer binding per pipeline is supported. All
the atomic counters identify an offset within this buffer. The shader
is modified to include a storage buffer definition with
`uint counters[];` as the only field.
A compiler pass replaces atomic counter definitions with variables that
hold the corresponding offset parameter, as well as changing atomic_uint
types to just uint (as the offset). Where an atomic counter variable is
used, it is replaced with the offset variable (plus the array index, if
array). At the same time, built-in `atomicCounter*` functions are
replaced with a corresponding `atomic*` function and
`memoryBarrierAtomicCounter` is replaced with `memoryBarrierBuffer`.

Fix constructing void array zero nodes
Correctly sized void arrays can be needed after parsing has recovered
from an error and the code is trying to evaluate the constant value of
a node. Since now we just have a generic EOpConstruct op instead of
different ops for different types, we can simply remove the special
handling for void arrays in CreateZeroNode to create the arrays in the
correct size.

Replace reinterpret_cast with safer or no cast
When casting types to one another in C++, the weaker the cast,
the better.
This change replaces instances of reinterpret_cast with static_cast
or no cast where it safe and correct to do so.

Identify functions by unique id in BuiltInFunctionEmulator
Now that unique ids of all builtins are compile-time constants, we can
use them to look up functions in BuiltInFunctionEmulator. This is
simpler than using a custom struct with the name and parameters for
identifying functions.
This requires that we store a reference to a TFunction in those
TIntermUnary nodes that were created based on a function.
This decreases shader_translator binary size by about 6 KB on Windows.
