Uses the legalization pass recipe from SPIRV-Tools.
Also change -fcgl to disable both legalization and optimization.
Validation on some tests are turned off because of new image
instruction checking in SPIRV-Tools. Enabling them is a TODO.
-bump up dll version for fixed version
-show dxcompiler and dxil version number for dxc help message
-emit warnings for dxcompiler validator that container will not be signed
Right now we just do a load and then a store over of whole struct,
completely ignoring the storage class (and thus layout). This is
surely invalid SPIR-V, but we need this right now to enable some
workloads. Hopefully SPIRV-Tools will be able to remove these
loads/stores.
Updating associated counters for certain types is a TODO.
Previously we reply on Expr::isGLValue() to check whether an
expression is lvalue. That requires lots of ad-hoc fixes in
the CodeGen for missing/wrong lvalue/rvalue.
Now we use SpirvEvalInfo to calculate the lvalueness together
with the <result-id>. It is much cleaner.

If there are no return value specified in the source code for a
certain control flow path, just return the null value.
Previously always use OpReturn to terminate basic blocks without
explict return statement from the source code, which may cause
illegal SPIR-V generated.
This commit add checking for three HS/GS rules:
* HS entry point should have the patchconstantfunc attribute
* GS entry point should have the maxvertexcount attribute
* GS stream-output objects should be inout parameters
This change removes new Load variations (LoadHalf, LoadFloat, etc) for RWByteAddressBuffer/ByteAddressBuffer methods and add templated Load intrinsics. This templated Load only works on scalar or vector types, and its variations (Load2, Load3, Load4, etc) do not work with templates and work as it did before (only storing uints). For Store operation, you can store any scalar or vector types of up to 16 bytes, while prior to 2018 Store only supported storing uint scalar.
[[vk::push_constant]] can be attached to a global variable of
struct type to put that variable in the PushConstant storage
class.
PushConstant should be of OpTypeStruct type with std430 layout.
This change is to add fixed width scalar types in HLSL 2018.
These types are: int16_t, uint16_t, int32_t, uint32_t, float16_t, float32_t, and float64_t.
Prior HLSL versions do not support these fixed width types.
This change also renames /no-min-precision command line option to /enable-16bit-types. int16_t and uint16_t are only allowed with this mode.

* Translation of DeviceMemoryBarrier(WithGroupSync)
