Fix 'continue' in GLSL loops.

The test expression of a loop is placed between the TEST and ENDWHILE
shader assembly instructions, and should no longer be affected by the
cleared execution mask of a continue statement. Thus TEST should always
be emitted, even for non-deterministic loops.

Other masks should still apply, and work recursively, so the
'whileTest' boolean to disable all masks during the test expression
evaluation has been replaced with a stack to restore the continue mask
at the TEST instruction.

Generate an error when trying to clear an incomplete Framebuffer

Calling ClearBuffer* on an incomplete framebuffer was crashing
because a depth clear assumes 4 bytes per pixel and the type of
an incomplete framebuffer could be anything, which is potentially
smaller than 4 bytes, so memory was written out of bounds.

ClearBuffer* now also checks for completeness, just like clear
already does.

From the OpenGL ES 3.0 spec, section 4.4.4.4
"Effects of Framebuffer Completeness on Framebuffer Operations

Attempting to render to or read from a framebuffer which is not
framebuffer complete will generate an INVALID_FRAMEBUFFER_OPERATION
error. This means that rendering commands (see section 2.6) ...
will generate the error INVALID_FRAMEBUFFER_OPERATION if called
while the framebuffer is not framebuffer complete"

And from the OpenGL ES 3.0 spec, section 2.6 Rendering Commands
"GL commands performing rendering into a framebuffer are called
rendering commands, and include the drawing commands Draw* ...,
as well as these additional commands:
• BlitFramebuffer
• Clear
• ClearBuffer*"

Fix deterministic loops within conditional blocks.

Deterministic loops use the first scalar of the SIMD register used as
the loop index, for addressing arrays. This means that operations on the
index register should not be masked (i.e. it should be treated as a
scalar).

Previously we were still masking it based on conditional statements, and
we didn't disable the masking altogether (using the 'TEST' instruction)
for the loop initialization and initial test.

Also, non-deterministic loops should not have any execution masking
disabled, so don't emit 'TEST' for them.

Fix clamping of NaN values.

We pass integer uniforms as floating-point ones, which can cause an
exception when converting them to fixed-point values. For example an
integer value of -1 would be 0xFFFFFFFF which is Not-a-Number in
IEEE-754 floating-point and can't be cast to an integer.

In this case we don't actually care about the result because the fixed-
point number is only used by the fixed-function pipeline. A safe but
still fast way to compare floating-point numbers including NaNs is to
treat them as one's complement integers, which can easily be converted
into two's complement representation.

Also rename bitCast<> to bit_cast<> to match the C++20 function.

Vulkan has multiple synchronization objects:
- Events, which provide synchronization between commands submitted
to the same queue, or between the host and a queue.
- Fences, which insert a dependency from a queue to the host
- Semaphores, which insert a dependency between batches submitted
to queues

For now, SwiftShader will treat these synchronization primitives as noop, since:
- Commands will be executed in order
- SwiftShader currently only supports 1 queue

On linux, clang is unable to find the Cast() function used in the
templated destroy() function unless it has already been defined
before the template function. This forces us to make sure all
Cast() functions are available, but simply adding the vulkan objects'
header files in VkMemory.h would cause a circular dependency, which,
while it would be properly guarded by the preprocessor directives,
wouldn't guarantee any include order, due to the nature of circular
dependencies. So, to fix the issue, a new header file, called
VkDestroy.h was added, which can depend on all vulkan objects' header
files without creating a circular dependency.

Also fixed some warnings.

Vulkan dispatchable objects

Vulkan has a few dispatchable objects: Instance, Device, Physical Device,
Command Buffer and Queue. These objects, when loaded through an ICD, are
constrained to have a bit of memory allocated at the beginning of these
objects to contain loader data.

In order to do this, a wrapper class, DispatchableObject, was created to handle
pointing directly to the loader data when casting to the associated VK handle
and similarly back to a pointer to the internal object. Note that Queue, being
allocated within another object, and not directly through the API, simply have
the loader data at the beginning of the class, without requiring a wrapper class.

Also, since all these object are allocated through a custom placement new
operator, they have to be deallocated through an associated destroy() function,
so the DispatchableObject destructor is deleted, in order to prevent these
objects from being released any other way.

Migrate to using <log/log.h> since Android O (API 27)

Starting from Android O, <cutils/log.h> is planned to be deprecated in the
future. The use of the original <cutils/log.h> is split into 2 header files.

Per Treble team's (b/78370064) description, <log/log.h> is for native shared
libs or executables, and <android/log.h> is for app JNI.

So a conditional preprocessor is put in place to look at the
ANDROID_PLATFORM_SDK_VERSION definition. If the value is less than 27, means
it's Android N or older, and it ought to include <cutils/log.h>.

Otherwise, it should be 27 (Android O) or any greater version, and it's
supposed to include the new <log/log.h> file.

If ANDROID_PLATFORM_SDK_VERSION is not definied, Andorid build system catches
it and stops the building process with an error message.

Add SWIFTSHADER prefix to Android.mk variables

This commit replaces use_subzero with SWIFTSHADER_USE_SUBZERO and
unsupported_build with SWIFTSHADER_UNSUPPORTED_BUILD in Android.mk so
that it can be consistent with other variables.

Build fix

Made sure both LLVM and Subzero has the /src directory in their
include directory list. Removed unused ../ in front of "Common"
includes as a cleanup.

Failures in dEQP using SwiftShader with LLVM 7.0 were caused by unsafe
floating point math optimizations, which are more aggressive than with
LLVM 3.0.

Work around stack probe issue.

LLVM fails to resolve the __chkstck function for probing the stack when
it's larger than 4 kB. We don't need it for SwiftShader because newly
created threads have 1 MB of committed stack memory.
