This uses APIs that are not available on Win7. Since this is a build-time
configuration, and since we can't use the SDK version as an indicator
(since you can support Win7 via new SDKs), a new option is added to allow
disabling it, to maintain Win7 support if desired.

SIGSEGV is used by Vulkan API trace layers to track user changes in
device memory mapped to user space. Now with drivers such as Zink, GLES
applications are translated into Vulkan API calls and therefore it is
possible to be tracked by Vulkan api trace layers.
Blocking SIGSEGV hinders one of the memory tracking mechanisms used by
such layers.

This workaround looks actually broken. We added it in the past
because otherwise the game would just report 3GiB of video memory
(ie. size of GTT on SD). Though, with this workaround enabled, the
game explodes in memory easily.
One theory is that because we fake integrated GPUs as discrete GPUS,
and because we report 6GiB of VRAM (ie. driver redistributes memory
for small carveout), the game thinks there is 6GiB of VRAM only and
then keep allocating stuff.
People reported that the memory explosion is gone without this
workaround applied and I confirmed this myself.

As long as we left-shift the unsigned version, this has no undefined
behavior and is fewer instructions. The only tricky bit is that a right
shift of a negative number is technically implementation-defined (not
undefined) behavior in C. However, if it's ever anything other than an
arithmatic right-shift, there's lots of other places where Mesa will
break today.

Due to how alignas is defined, it itsn't allowed to use it on a struct,
it needs to be used on the first member instead. So move the declaration
in those cases.
This still leaves the ALIGN16 macro using compiler-specific directives,
because it's a lot of work to untangle the above. This probably deserves
its own MR.

Since we now require C11 and C++14, we can use the standard
static_asserts from the standard library instead of rolling our own
compiler-specific versions.
To avoid needing scopes around usage in switch cases, keep the
while-wrapping from before. This means it still can't be used outside of
functions, but that should be fine; we should probably just use
static_assert directly in those cases anyway.

This macro kinda complements util_is_power_of_two_*, but is implemented
as a macro. This means that it can expand to a constant integral
expression, and thus be used in static_assert.
Because we don't really need the added complexity, this doesn't handle
zero correctly. But that's OK, because the call-sites will.
