This adds or changes binding/location decorations in 100s of shaders.
It also allows more output (spv.register.autoassign.rangetest.frag)
due to allowing ioMap() to fail.
* Changed unit tests to only record known the validation pass/fail
status
* errors are output as part of the failure message if the result is
unexpected
* can turn off validation for each test individually
* Moved some SPV_KHR_vulkan_memory_model tests to be compiled for Vulkan

Consider the following code:
layout(constant_id=0) const int Y = 1;
layout(constant_id=1) const int Z = 2;
layout(constant_id=3) const int X = Y + Z;
Previously, it would produce SPIR-V decorations like this:
Decorate 21(Y) SpecId 1
Decorate 22 SpecId 3
Decorate 33(Z) SpecId 0
This seems inaccurate, since the spec constant `X` that is dependent on
the two others did not get a name in the SPIR-V decorations. This behavior
may potentially negatively affect shader introspection capabilities.
This change alters the behavior to always add a name, which results in the code
above producing the following decorations:
Decorate 21(Y) SpecId 1
Decorate 22(X) SpecId 3
Decorate 33(Z) SpecId 0
These introduce limited support for 8/16-bit types such that they can only be accessed in buffer memory and converted to/from 32-bit types.
