While LLVM 8 provides CreateBinaryIntrinsic() and CreateUnaryIntrinsic()
as part of the IRBuilder<> API, they implicity append the operand type
to the intrinsic name. This only works for 'abstract' intrinsics such as
'sqrt'. For intrinsics corresponding to specific native instructions,
it causing symbol resolution to fail. This change adds
createInstruction() functions to simplify the creation of these native
intrinsics.

Also remove some macros which were needed for compatibility with LLVM 7.

The VK_STRUCTURE_TYPE_MEMORY_DEDICATED_ALLOCATE_INFO extension structure
is safe to ignore for Linux and Fuchsia.

We already ignored it for private allocations (see vkAllocateMemory).
Some drivers can do a better job of allocating if they know that a
VkDeviceMemory will contain exactly one object with known properties.
This is the case for NVIDIA, but not SwiftShader.

For external memory, on some platforms (including Android) the shareable
object isn't just a flat blob of memory, it carries format/dimensions
etc. The AHardwareBufferExternalMemory implementation in
VkDeviceMemoryExternalAndroid.hpp obtains the image/buffer from the
VkMemoryDedicatedAllocateInfo structure to pass it to gralloc.

External memory on Linux and Fuchsia are just flat memory allocations,
so on these platforms we can ignore the dedicated allocation info.

Before this commit, when debugging with the ReactorDebugInfo feature,
variables were being incorrectly displayed in the debugger. For
instance, given:

Int a = 1;
Int b = 2;

The debugger would not display 'a', and would display 'b' as containing
the value '1'. The reason for this was that while the Int constructor
for 'a' was executing, we invoke boost::stacktrace() to determine the
variable's source location (file and line number); however, the stack
trace would return the return address of the constructor call, which
would be on the next line -- that of 'Int b'.

To fix this, knowing that all ReactorDebugInfo emits come from function
calls in Reactor code, we assume that all backtrace addresses point to
the next instruction following the call, thus we subtract 1 from these
addresses. When resolving the file and line number, this gets back the
previous instruction's location. There are likely corner cases where
this doesn't work, but it's better than what we have now.

Changed the algorithm to compute the copySize value.

Earlier, in the isEntireRow && isSingleSlice case we were putting
copySize = imageExtent.height * imageRowPitchBytes which is wrong
in the case when imageRowPitchBytes is the same as
bufferRowPitchBytes, but also contains some extra padding.
For example, for copying to the whole 127 x 64 texture with RGBA8
format with bufferRowPitchBytes = 4 * 128 and buffer size =
4 * (63 * 128 + 127) will produce an assertion error.

Some of the files for LLVM 10 were conditionally compiled for Debug
builds; however, two of these were also in the main source list:

${LLVM_DIR}/lib/Analysis/RegionInfo.cpp
${LLVM_DIR}/lib/Support/Debug.cpp

This lead to linker errors for missing symbols when, for e.g.,
Support/Debug.cpp was built because Support/circular_raw_ostream.cpp
was not compiled.

I decided to just fold in these few Debug-only sources into the main
list to keep it simple and similar to how LLVM 7 was being built.

X11/Xlib.h defines Bool as a macro, which clashes with Reactor's Bool
class. This X11 header is also included by vulkan.h, vk_icd.h, and
EGL/eglplatform.h

Previously we undefined Bool in various places. It's not possible to
just undefine it in Reactor.hpp because one can have headers following
the inclusion of Reactor.hpp which redefine it (note our convention is
to include platform headers after project headers).

Since X11 is only needed in select places related to the windowing
system, we can instead avoid the use of these headers in other headers,
and only include them in .cpp files where necessary. Note that
vulkan_core.h contains the whole plaform-independent Vulkan API, so it
should be used instead of vulkan.h for all non-WSI code.

Surface::decodeASTC() was empty, and ENABLE_ASTC hard-coded to 0, so we
never actually supported ASTC for OpenGL ES.

We won't need it in the future since this legacy code is deprecated and
set to be replaced by SwANGLE (which supports ASTC LDR at the moment).
Also note ASTC LDR doesn't become mandatory until OpenGL ES 3.2, and
this legacy code lacks compute shaders to even support ES 3.1.

While e.g. "CmdImageToImageCopy" was slightly more explicit, it can
leave one searching for the vkCmdImageToImageCopy API call.

Instead of updating images every time we write to them,
this cl adds a dirtiness mechanism, which will mark an
Image object as dirty for specific unique subresource
regions and then only actually perform the required
task (cube border update, decompression, ...) once the
image memory is accessed for reading.
