Fix materialization of function arguments

Subzero does not appear to preserve function arguments passed in as
registers onto the stack by itself. Any scratch registers can get reused
for local variable register allocation.

This workaround simply materializes each concrete Reactor variable
constructed from an argument on definition. It does not ensure that
arguments turned into variables at a later point are properly preserved.
Also this solution does not centralize the materialization, making it
bug prone when new concrete Reactor types are implemented.

Elide single basic block variable materialization

Variables which are only used within a single basic block and don't
have their address taken, don't require allocating stack memory.
Instead they can track the latest rvalue that has been assigned to them.
Allocating stack memory is necessary for variables that are assigned to
in divergent basic blocks since there is no single rvalue to track after
the merge point (unless we inserted phi instructions, but that is
outside of the scope of this change).

Because Reactor can't look forward to check whether a variable will be
used in divergent basic blocks, we keep the set of variables that may
not have been materialized yet, meaning they have no stack address yet.
When a branch is encountered, they are all materialized.

Variables not yet materialized at a Return() are 'killed' to prevent
materializing afterwards, which would cause the terminator ret
instruction to not be the last instruction of the basic block.

Note that this change creates a dependency of the Nucleus
implementation on Variable, which is currently defined in a higher
layer in Reactor.hpp. Since Variable doesn't depend on anything else
in Reactor.hpp it could be made part of Nucleus, or an in-between
layer could be added.

Renderpass multisampling resolve

According to the Vulkan spec:
"If pResolveAttachments is not NULL, each of its elements
 corresponds to a color attachment (the element in
 pColorAttachments at the same index), and a multisample
 resolve operation is defined for each attachment. At the
 end of each subpass, multisample resolve operations read
 the subpass’s color attachments, and resolve the samples
 for each pixel to the same pixel location in the
 corresponding resolve attachments, unless the resolve
 attachment index is VK_ATTACHMENT_UNUSED."

Note: This cl adds support for multisampling, but
      requires syncing before performing the resolve
      operation. The intent is for the next cl to move
      the resolve to Renderer::finishRendering(), in
      order to avoid having to sync when it's not
      necessary.
