…raversers. UniformTypeChangeTraverser and MoveNonSamplerUniformsIntoStruct only excluded samplers and matrices, so they happily visited the symbols representing whole `layout(std140) uniform` blocks (EbtBlock) and `uniform Foo foo;` struct instances (EbtStruct), rewriting them to vec4. Once that happened, spirv-cross emitted unnamed placeholder uniforms (e.g. `uniform vec4 _1195;`) and the matrix multiplies collapsed to scalar nonsense, then bgfx asserted on the empty uniform name (`Identifier can't be empty.`). Restrict both traversers to scalar/vector basic types (Float/Int/Uint/ Bool) so blocks and structs are left intact. Also throw early in CollectNonSamplerUniforms if a uniform name is empty, so any future regression surfaces in the compiler instead of as a deep bgfx assert. Add a TODO in CMakeLists.txt to point SPIRV-Cross back to the upstream BabylonJS fork once the corresponding PR there is merged.

Use a generated shader to check no mandatory glsl function missing in spirv-cross when using WEBMIN flag.
BabylonJS/SPIRV-Cross#10
Fix
UniformTypeChangeTraverserandMoveNonSamplerUniformsIntoStructwere also visiting wholelayout(std140) uniformblocks (EbtBlock) anduniform Foo foo;struct instances (EbtStruct) and rewriting them tovec4, producing unnamed placeholder uniforms in the spirv-cross output and aIdentifier can't be empty.assert in bgfx. Both traversers are now restricted to scalar/vector basic types (Float/Int/Uint/Bool).CollectNonSamplerUniformsalso throws early if a uniform name is empty so future regressions surface in the compiler instead of deep in bgfx.
